Never liked them. Modern smartphone is convenient , but a keyboard would be nicer

It's my wishful thinking

You should really try cobol, lisp, ada, or erlang. Dead languages are the best

While you describe the way how error correction works, there are other factors you fail to notice.

It is widely known, that for each physical qubit T2 time decreases when you place it among other. The ultimate question here is: when you add qubits, could you overcome this decoherence with EC or not.

Say you want to build a QC with 1000 logical qubits and you want to be sure that the error rate doesn't exceed 0.01% after 1 second. You assemble it, and it turns out that you have 0.1%. You choose to use some simple code, say 7,1 and now you have to assemble a 7000 chip to execute 1000 qubits logic. You again assemble it and the error rate is higher now (due to decoherence and crosstalk). But the question is how much higher? If it's lower than your EC efficiency then you just drop a few more qubits, use 15,2 code and you are good to go. But what if no?

It was shown this year for how many, 47 qbits to scale? How could you be certain this will stand for millions and billions?

But who guarantees that ec will overcome decoherence, introduced by this number of qbits? Not a trivial question that nobody can answer for certain

If qbits double every year

And then we need to increase coherence time, which is 50ms for the current 433 qubits large chip. Error correction might work, but might not

Ok, I decided to dive into it today again and look what I've found:

1. They still demonstrate supremacy to each other proving that their setup couldn't be simulated. These 433 and 1000 qubit processors are good only for one purpose: to simulate itself.

2. Photonic QC still estimates hafnian billions times faster; if only this mathematical structure appeared to have any practical meaning

3. They demonstrated that toric codes might be effective

1000 qubits? Where? Last time I checked it was 50 qubits for 200ms

russians also want to buy mcdonalds, iphone and porsche and not live gulag life.

First and foremost, Russians do not want to kill Ukrainians. But that's like saying that people do not want to pay 40% of their income on rent and utilities. Nobody cares what people want

In general yes. Just a daily reminder of our dystopian days
