What’s the current thinking on scaling? Last time I looked a couple of years back there was serious people arguing that quantum computer couldn’t scale up to useful sizes?

Of course, if quantum mechanics fails, or certain types of very unexpected noise occur, all bets are off. The most amusing possibility: quantum mechanics fails, but quantum computing remains possible. (There are actually mildly plausible models where this happens.)
Unfortunately, the most widely distributed critical articles are, like many of the most widely distributed praising articles, largely clickbait.
