>currently they don't have even 1 logical qubit

wut? different QEC produce differently sized logical qubits and there are absolutely machines with enough physical qubits to amount to a logical qubit:

and realized QEC is definitely not far off

>for quantum computer to be of any use it should have >10k logical qubits

i'm aware and yet it's false to claim that these things don't compute. for the time being they're noisy computers but they're still computers.
