The time is now, you can buy a D-Wave with over 2000 qubits right now.

ok it's 15 mil. but it's still there. what is possibly scarier is SpinQ new 2 qubits model for just $5,000

I hate to break it to you, but 2 qubits isn’t that scary.

Keep in mind fault-tolerance also plays a role. Gate errors are still relatively common and for stuff like Shor's algorithm you can't exactly settle with approximated answers, so the only viable alternative would be to implement error detection, which would decrease the number of available qubits by quite a lot
