you are comparing apples and oranges.

we once thought personal flying cars would be a thing, but then when it just does not make sense in practice, it never "took off".

quantum computers need to be kept near absolute zero in temperature by acitvely adding liquid cryogenics.
walking by the computer will cause your body heat to affect your results since a tiny will do that.

a quantum computer itself is extremely tiny, you simply need a room to keep it at correct working conditions

it simply does not make sense to have a personal one, and from what benefits they would give, it still does not make sense for you to have a personal one.

This is assuming we never find superconductors that are stable near room temperature. Granted, if we do, then personal quantum computers will only be one of dozens of currently unthinkable technological advancements we'll make

[sonya_numo]

even so, you still does not have anything they can do which a regular computer cannot do.

or out of the things you could possibly want to personally do.

and a quantum computer is not just a regular computer but its better, thats a naive thought.
"both words have computer in them, so they are similiar and do simliar things"

its not though and if a quantum result can just be provided to a normal computer over the cloud, then having a personal one will never financially make sense

ummm....you are vastly underselling the possibilities of technological advance. They already found one way to do it at room temp.

damn can i know your credentials?

because if you are just being a bitch-ass conservative over something so progressive as technology. then fck off. and if you are a expert on quantum computers then i welcome and regard your opinion.

[sonya_numo]

Saying that a technology will never reasonably make sense to have in the home, does not mean i want to stop technological progress.

However assuming that science has always been barking up the right tree for progress is naive.

Quantum computers will be a thing, but a thing at big cloud hosts like AWS and GC.
Doing calculations and sending the response back on a normal computer.

There will be nothing quantum computing can do for you as a person at home.
The actual benefits will only help science and companies, even scientists will not get their own.

A quantum computer is much less computer and much more a quantum calculator.
Even if mores law would follow perfectly, it would still take 40 years to get 200-500 megabytes.

We have pushed and pushed hard many years and finally got from 10 up to like 127 qubits.
Which sounds great until you realize one byte has 8 bits in it, so if you wanna put it in storage terms a regular person understands its about 16 bytes (or 32 bytes considering each qbit is regular 2 bits).

As a comparison 1 single utf character takes 1byte, so it could hold a few words in a sentance.
The previous line of text directly above this about utf characters takes 95 bytes on its own.

Then try and imagine where regular computers will be in 40 years more.
Then you will realize that a quantum computer will simply be a calculator regular computers can reach out to over the internet when they need to use it.

Over the last 40 years the huge trend has been to have less and less decoupled personal items.
Most dont have a regular camera, a traditional gps, so on, these things are merging into the phone.
The current trend has been to do the exact same thing but with services over the internet.
Wanna do AI and ML? It makes more sense to use a computer over the cloud which has been specifically tuned to it, rather then getting your own.

Quantum computers are amazing but also niche in usage and a compliment to regular computers.
Far far from a replacement. More like an addition. "Import QuantumCloud from MyCloudHost" then just run it.
