Have you taken the time to study Bitcoin and the mining? I recommend keeping your arrogance aside and studying for a change. Even you emit CO2 so why don't you extend high horse thinking towards yourself? Learn something.
There's no guarantees that breakthrough is coming anytime soon. Scaling up the number of qubits in a processor is very hard and it's why progress has been pretty slow over the last decade.
Not 100% sure what you mean but it depends on who makes it. A government would have better things to do with an encryption destroying quantum computer than crashing blockchains. Personally I wouldn't crash crypto coins immediately, I'd make some money off them first then wipe it out.
Also I was talking about the future. It may be impractical for centuries to make a quantum computer large enough to factor large current cryptographic keys. Last I read the difficulty of maintaining coherence has a non linear relation to the number of qubits involved.
Yes. OP is human and learned from their mistake. They can start over with a new Google account and try again. If the Google ban hammer falls again then it's time to tell Google to f-off and move to another platform forever.
You joke, but bans on cash have been proposed for decades. Naturally with CBDC, the government could better control who could transact and for what purposes.
Same boat as you my friend :) I used to be a PHP developer now trying to transition to the JS world. I believe what we do from 8am to 5pm is the job but what we do from 5pm to 8am will move the needle. It is ok to start from scratch and let go because in 10 years from now your future self will thank you.
