I'd like to see quantum computers actually do anything practical, anything at all, instead of making wild promises of what they might or might not be capable of. Stop promising, start delivering.
Do you keep up with the development of QCs at all or are you just an eager consumer? They're only able to make QCs with a small number of qubits at the moment and can't add more without running into sound disruption issues so it's a ways away from being able to do anything practical.
I'm far from convinced about QC yet, but the first transistor was in 1947 and now the CPU in my phone has over 3 billion. Looks like they took 30 years to get from that first transistor to the TMS 1000 with 8,000 transistors on it.
I'm on Mobile and having a hard time finding the link but I'm pretty sure the Google quantum computing team (and probably others) have built low qubit computers that have factored numbers into it's prime factors.
With Shor's algorithm (the thing that would make this headline about "Quantum computers will break the encryption that protects the Internet" true) AFAIK the answer is that quantum computers have found 21 = 7 x 3
Because of interest in using quantum computers to factor big numbers there's a reason to do something other than Shor's algorithm with a big machine that can't run Shor's algorithm and thus get a big impressive number. This approach has factored six or seven digit numbers. Which your PC could also trivially do, and it doesn't use Shor's algorithm either.
