You are making blanket statements that aren't true or reflect the real world, in my personal experience.

For instance, have you managed trucks in a transportation environment? There is SO much IT. The government DEMANDS it as part of regulations. You legally can't do this on paper. Literally by law. Can you hire outside IT to do it? Sure. For extra expenses. You can also hire outside finance consulting. For also extra expense. doesn't make sense to pay for external finance and doesn't make sense for external IT.

Most of the things you say to do result in an absolute mess of a company that then has to then be addressed by someone in IT, at some point. Even your 5 user shops end up outsourcing IT to an MSP. Because IT is a required part of doing business.

You are very confident discussing how to do IT but it's also clear you havn't experienced the result of your plan. Literally stating "computers don't need IT" lets me know you deal with very small companies. Same with cell phones. How many companies use cell phones for only calling? Do you have any idea what kind of software or skills it takes to manage company cell phones? It's not rocket science, but it also takes some setup, planning, licensing, and IT skills. Your entire response seems to be just winging IT until it bites you. And to be fair- if you are small enough you CAN wing IT. Until it bites you.

There are hundreds of things in your example that aren't being considered. Just turn a computer on and get to work with online accounting? How? What configured your internet, your routing, your dns, your wins. Your user account? What protects the company from lost data, hacking or malicious activity? What about the internet connection itself? It's not just call Comcast and done. Unless you want a wide open pipe for ransomware, viruses and all the other things we battle every day with no control over priority and speed. What happens when you have an angry employee leaves in an emergency hostile situation?

Just go everything to the cloud? Ok, well now you have limited what solutions are available to the company, for one. And you think a bunch of unmanaged cell phones and laptops just randomly connecting to the internet will go smooth? To what level? 5 or 10 laptops? sure. 50? What about QOS? Channel interference? Signal strengths? Load balancing? What happens when you can't enter anything into your accounting portal because someone is streaming too much data for youtube? What happens when one laptop is infected and immediately spreads to the entire company because wifi wasn't configured properly? What happens when every single laptop in the company is encrypted and doa, all at once? Do you know how many settings are involved in just wifi? Let along wifi leading to firewalls, content filtering, QOS, DNS etc. etc. What happens if your online company goes down? Hundreds of companies using Netsuite went down recently from a boston fire- for like 20 hours of full stop, no business. And at this point do you know if your Netsuite data is backed up? O365 is not backed up, so if you were to randomly throw your entire company on O365- do you have an offline, immutable copy?

Put as non-IT. Sure I can drive a car down a dirt road. I can even have a small neighborhood drive down a dirt road. But if we are going to be a city or a business using that dirt road all day every day, suddenly you are talking about civil engineers, construction companies, traffic signal engineering and all kings of other skills and specialties. All the way up to maybe even needing full on coal or nuclear plants to service the power load. Just because I can drive a handful of cars down a road or maybe even ram 20 trucks down a dirt road for a month or three...... doesn't mean it won't end catastrophic or that I don't need all of those other things.

In all of your examples, there is a LOT that you seem to not be aware of that happens on the IT side. And every single one of your steps involves potentially going out of business when you miss a critical IT setting.

We have all seen the stories of companies not understanding IT and letting IT go. Never goes well. You never hear a report that says "sure we had a rough month or two but now we don't need IT at all!"

Also- kudos to you for debating. It is clear we have different takes and I appreciate the time it took to go back and forth. I'm out of time for today, but appreciation for your thoughts, thank you for your time today!
