Scott Aaronson writes the very interesting blog, Shtetl-Optimized. Aaronson is a reasonable voice in the quantum computing world.
Here is an interview that Eli Ben Sasson (the Starkware guy) did with him about how much of a threat quantum computing may be to Bitcoin and on what timeline.
It's pretty interesting: the first half is mostly Aaronson explaining quantum computing and how to evaluate the various announcements that companies in the field make.
The main takeaway that I got form it is that Aaronson pretty firmly believes that quantum computing development no longer has any theoretical hurdles, and that it has largely become an engineering problem: build quantum computers with more good qubits.
