The field has had 40 years of maturing. Experimentation on QC started in the 1980's. At what point are we going to be factoring numbers or (more realistically) simulating chemical interactions?

Real progress in this field is very easy to measure. It's based on number of effective qbits of computation. That is just a metric where QC is failing to deliver so badly that everyone in the field wants to deny its existence.

Unfortunately, the level of investment in QC is very much outsized compared to the level of progress. These things should rise at the same time. More promising areas of science can get the investment that is otherwise being sucked into QC.

This is something that people like to say but is never true. Impact on the outside world for new technologies is almost always a sigmoid function, not a heavyside function. You should see some residual beneficial effects at the leading edge if you have something real.

Plenty more progress measures (decoherence, gate fidelity/error rates) to use that we have made significant progress in over the last 10 years.
