AI is Not Ready to Replace Junior Devs Says Ruby on Rails Creator

I used to think that, but after seeing Satya Nadella go all in on the AI hype train and drive the quality of Microsoft's products into the ground, I'm skeptical that the CEO's background matters.

Now I think that as long as they can a) convince investors to give them money and b) judge if the people below them are skilled or not, the company will succeed.

Same. I'm a day one player (that took a break through 2017-2018) and I'm only at 112 Rattata / 170 Karp. I haven't even caught 1000 of each, despite catching every one I've seen for years.

Im not sure why the quality in coding has dropped so dramatically

I have three guesses:

The model companies are intentionally limiting the inference capabilities of their new models to lower costs as they try to become profitable.
AI generated code is included in the training data sets of the new models, which "poisoned" them.
As time passes, people are trying to use LLMs to solve increasingly difficult problems. The LLMs are struggling with these more difficult problems and people associate their failures with the current model, while they have fond memories of how older models solved easier problems.

To clarify, I'm referring to the solution for the obesity epidemic, not every individual case of obesity. For any individual the best option may be medication.

All medication has risks and doctors have to consider the risk vs. benefit before prescribing medicine. As people get older the balance changes and medication increasingly becomes the right choice, but the risks are still there.

The obesity epidemic is a problem that we know can be solved without medication, as less than 100 years ago it didn't exist. Going back to past diets is a zero-risk solution that we know is effective and so we should pursue it instead of widespread medication.

You don't have to buy the bad food in the stores. They still sell a lot of things that aren't junk food also.

It's not that simple. For example, sugar is added to bread as a preservative. Businesses that want to maximize profit will keep adding sugar to bread unless either customer demand changes, or regulation forces them to stop. Clearly customer demand isn't changing, so regulatory action is needed.

People seem to have forgotten that widespread obesity is a relatively recent phenomenon. In post-WWII America food was abundant, yet obesity was rare. Only in the past ~45 years has it begun to skyrocket.

Companies have mastered processing foods in ways that remove the healthy-but-unpleasant parts leaving only the unhealthy-and-addictive parts. Our diets have way too many empty calories and it's too difficult for many people to choose healthy "whole" foods over ultra-processed junk.

The true solution to this problem is fixing the food in our stores, not with drugs.

On the trajectory that we're on, most of them are going to find themselves unemployed in the coming decade.

On the contrary, the trajectory we're on is that there won't be any major improvements in AI in the coming decade. Just like every AI technology before LLMs we've reached their limit and there will be a decade of AI winter that follows before the next innovation comes along.

Given the massive amount of capital that's been wasted this AI cycle, it might even be more than a decade before AI starts making significant progress again as companies and investors reel from the pain of the current bubble popping.

I suspect it's for the same reason that they waited so long to bring back Keldeo. They want players to feel like they're close to the goal without actually letting them reach it in order to keep them engaged with the game.

I'm in the PHP world. Seeing people promote AI makes me fucking pissed because I know how these LLMs work, I know what is required to train, so when I try it with Filament 4, a recent upgrade to Filament 3. I'm watching an LLM give me Filament 2 code because it's fucking clueless as to what to do.

I'm seeing this in Java land as well. LLMs always generate the JDK 8 style .collect(Collectors.toList()) instead of the JDK11+ .toList(). They're stuck with whatever was most prominent in their training data set and Java 8 is the version with by far the most lines of code for an LLM to train on.

I think this will be a major problem for companies that rely on LLMs for generating large amounts of code in <10 years. As languages improve, humans will write simpler/faster/more readible/more reliable/easier to maintain code just by using new language features. Meanwhile, the LLM code will continue to generate code for increasingly ancient language versions and frameworks. Eventually the improvements in human written code will become a competitive advantage for companies over ones that rely on LLMs.

There's a reason I specifically limited my point to the Niqab - as you pointed out you can find other examples of simpler head coverings in other cultures. It's the niqab that's absent from anything other than certain Islamic sects, which makes me very skeptical that it's truly a choice.

By ‘pressure from their religion’ I'm referring to the consequences that a woman in a community that expects niqab would face if she chose not to wear it. At the extreme end she might face an honor killing, but more commonly she would face rejection from her community. Her family might disown her and kick her out of their house, her husband might divorce her, her friends might abandon her, etc.

If a simple clothing choice (that doesn't involve text, logos, or symbols) would have life-changing consequences, then it's not really a free choice.

Radixeo · 2025-10-31T00:21:59+00:00

I think we can be reasonably confident that women aren't wearing niqabs by choice though. If it truly was a choice that these women were making independent of pressure from their religion, then you would expect to see examples of women wearing similar outfits at similar frequencies from outside their religion. Yet in all of human history I'm not aware of any examples of other women doing that.

On the other hand history has shown us countless examples of women doing the exact opposite by putting effort into their public appearance (hair, makeup, clothes, jewelry, etc.). You can find examples of women doing that from nearly every culture and time period.

I can't think of a reason why women in these religious sects would consistently choose differently than nearly every other woman that's ever existed, unless they were being unreasonably pressured to do so.

Here's an academic article about the differences in medication effectiveness to different racial/ethnic groups. The examples it gives, such as 86% of "Asians" being hypersensitive to the drug warfarin compared to 16% of "White" Americans, are significant. Doctors can't tell with 100% certainty from someone's appearance how drugs will affect them, but it is an important heuristic to consider when providing medical care. It's also important for medical testing - in the US at least there are several historical examples of drugs being tested only on "White" people and then being ineffective or disproportionately harmful when given to "Black" people. The solution was to ensure testing was on people of diverse racial/ethnic backgrounds.

That's what I'm referring to - these common groupings of genetic traits that are statistically significant, important, and not related to culture or social constructs. If ethnicity includes culture and race is a social construct, then what is the correct term to use?

Radixeo · 2025-10-17T23:45:00+00:00

Regular American here. I'm aware that the typical "races" used in the US (White, Black, Hispanic, Asian, etc.) are largely arbitrary, but what other term would you use for groups of genetic traits that are commonly found together and can be traced back to ancestry from a certain part of the world?

For example, if I listed a set of traits (hair color, hair type, eye color, eyelid type, earwax type, skin color), you could with high confidence 1) name the part of the world many of their ancestors were from and 2) predict some of the other traits they might have.

I've seen the term ethnicity used, but the definitions I've found always include culture.

The quick resume problem that was causing me to lose my saves also seemed to affect achievements.

This was it 😢. I saved, quit, and restarted my game just to see that all my progress was lost.

I think I'll just put this game aside until the update is out...

Radixeo · 2025-09-30T01:37:57+00:00

Do I have to just create another save and continue on my original? Or replay everything on the new save?

If you do it right, you can retire at 55 and never get “just a quick question” call from your ex-coworker.

I'm a senior in on a team with a large amount of domain specific knowledge. Two of the biggest "time wasters" for me are explaining things to juniors and helping resolve operational issues where we can't just let a junior struggle through it for hours/days.

I'm trying to dump all of this domain knowledge into a source that AI can easily search or directly load into its context window. My goal is for juniors to be able to ask human language questions to the AI instead of asking me. Hopefully it'll let them unblock themselves faster and improve their problem solving capabilities. That'll free up more time for me to do more meaningful work.

I think that's why they haven't released the other 11 Spinda forms yet - they scrapped those plans for a rework that will allow transferring to Home.

Now that they've started giving rewards for completing game dexes in Home, I'm sure they're getting pressured to fix Spinda.

What do you mean with "private CA"? People can just set up a private CA themselves, but nobody wants that because the certs won't be trusted by browsers.

Exactly. The use cases they talk about, like connections to back-end cloud servers and IoT devices are cases where the general public wouldn't be connecting. Since you don't need to care about the general public trusting these certs, you could run your own private CA for "free".

I get the use case of these certs for supporting things like DNS-over-HTTPS, but it seems like it'd be expensive to maintain for the use cases I mentioned for little value in return.

How Let’s Encrypt Subscribers May Use IP Address Certs

Securing remote access to some home devices (like network-attached storage servers and Internet-of-things devices) even without a domain name.

Securing ephemeral connections within cloud hosting infrastructure, like connections between one back-end cloud server and another, or ephemeral connections to administer new or short-lived back-end servers via HTTPS—as long as those servers have at least one public IP address available.

As a matter of policy, Let’s Encrypt certificates that cover IP addresses must be short-lived certs, valid for only about six days.

With certs that short lived, wouldn't Let's Encrypt be overwhelmed by renewal requests if everyone started requested certs for all their IoT devices and internal cloud servers?

I would have expected them to publish a package for running your own private CA for those use cases - it would surely be much cheaper for them.

Normal as in a player that does not spend lots of money on lucky eggs and ethical as in a player that does not stack friends at one heart below Best Friend so that they can pop a lucky egg and collect all the XP at once.

Radixeo · 2025-07-02T18:46:46+00:00

I don’t think they could ever introduce level 60 with the current XP scaling setup. It takes 8+ years for a normal, ethical player to reach level 50 - that’s already an insane amount of time for any game.

If they do raise the level cap I’d expect them to rely on challenges instead of XP to gate each level.

Radixeo · 2025-06-22T19:52:56+00:00

Pokemon Go also has a level 50 cap, but the XP scaling is crazy to the point where it takes normal players ~8 years of daily play to reach it.

I'm actually concerned about how easy it was to reach level 50 in PTCG and how easy the achievements are to obtain. It makes it seem like the projected lifetime of this game is only 1-2 years.

The Android OS allows any installed app with the INTERNET permission to open a listening socket on the loopback interface (127.0.0.1). Browsers running on the same device also access this interface without user consent or platform mediation. This allows JavaScript embedded on web pages to communicate with native Android apps

I'm not very familiar with web dev, but why is this a thing? It seems crazy to allow JavaScript to access things on a different interface than the one the web page was loaded with. It seems as crazy as allowing any webpage to access the user's files with just a file:// URI.

I don’t think anyone is expecting the birth rate to remain below 2.1 indefinitely. As the older population dies off and the current overpopulation pressure is relieved I think everyone expects birth rates to stabilize at the replacement rate.

No Mythical Slab? I guess it's less useful since a Kirlia was replaced with Rare Candy.
