It is said to be at around 1000 qubits currently.

Predictions of the evolution of quantum computing are always wrong. They imagined it would take longer to reach 1000 qubits.

Previously, keys like Bitcoin were considered secure until 2040, now they are talking about 2030, some in 2028 or less.

I don't even know if there is already a BIP for this or whether they have already started working on it or not.
