So just because one person is cheating, it means all academics are cheating?
FWIW, most top-ranked CS conferences have an artifact evaluation track, and it doesn't look good if you submit an experimental paper and don't go through the artifact evaluation process. Things are certainly changing in CS, at least on the experimental side.
It's also possible that theorems are incorrect, but subsequent work that figures this out will comment on it and fix it.
The scientific record is self-correcting, and fraud / bullshit does get caught out.
It's not just "one person", there is wide-spread fraud across many disciplines of academia. The situation, of course, is vastly different across subjects/disciplines, e.g. math and CS are not really much affected and I would agree they're self-correcting.
I might agree they're self-correcting in the (very) long-term, but we're seeing fictitious results fund entire careers. We don't know the damage that having 20+ years of incorrect results being built upon will have... And that's not to speak of those who were overlooked, and left academia, because their opportunities were taken by these cheaters (who knows what cost that has for society).
