    I'm pretty careful with absolute words like that.
    There will need to be some major breakthrough in fundamental physics or material science to get the cooling apparatus much smaller than it is. That's highly unlikely.

    And quantum computing at higher temps won't work because the nature if it requires the atoms being measured to have zero resting energy.

    As there have been many scientific breakthroughs to get to where we are now with smartphones.

    That was a long series of inevitable predictable progress in engineering.

    This isn't a matter of ordinary engineering challenges to be overcome. What I'm talking about is something that upends our understanding of reality. Not just an evolution of what we already know, but a revolution that changes almost everything about our understanding of how the universe works. Discovering new unimagined forms of matter. Things like that.

    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.

    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.
