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?
There have been quite a few bad papers published to that effect, usually making statements that are either wrong or not even wrong. Someone seriously pursuing the skeptical argument is Gil Kalai (& this has perhaps helped push the field to address error models).

*_novel_ error/noise models. Last I heard, Kalai's work remained very speculative, but very good for the field. Landauer, Unruh, and Alicki all published reasonable critiques, though I believe every comment there is now well accounted for.

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.
