No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

The general computer didn't exist in 1927. Once it did, yes it was predicted and expected they would get smaller, more powerful, efficient, and common. There was no limitation of physics getting in the way of it.
Of course, every increment is predictable after you make the scientific breakthrough. Not before, though.
The artificial computer wasn't so much a scientific breakthrough as a conceptual one. It didn't require anything that didn't already exist.
The quantum computer does exist. And it's functional principles are built on physics not engineering. It's a fundamentally different situation.
If I'd be able to ever collect, I'd bet you $10K in an investment account, that in 10 human generations quantum computers still won't be portable personal devices.
Neither does this. You just don’t know about it yet. And the link I provided you with shows that.
Not true. Electrical currents are physics too. And quantum computers have hardware too.
What are your arguments for this? I’ve shown you that your central argument is already being addressed.
What exactly is this, that I don't know about?
And how does Moore's Law apply?
I'm not sure we're talking about the same thing.
“This” as in a quantum computer, the thing we were discussing. And the physics and engineering is something you don’t know about. For example, you didn’t know about nitrogen vacancy centers that are already theorised to make room-temperature quantum computing possible. On top of that there are many breakthroughs yet to be made that even current experts may not yet know about.
Moore’s law applies to predictions, which is the other thing we were discussing. Moore’s law was indeed an accurate prediction up until recently, but only after the breakthrough was made, like I also mentioned in my previous comment. I never said it applied to quantum computers.
But it seems to me that you’re just going on a hunch. I’ve tried to apply logic, reasoning and sources to no avail, so I think I will just leave it at that.
