Right, speaking as a lapsed mathematician, I definitely see errors or gaps in published work. Wiles’ original FLT proof had one. And yes these can generally be patched up. I’m not quite as alarmed as the author is, because generally a major false result would have all sorts of alarming ripple effects and implications which would be pretty easy to spot. FLT is an extreme example where literally anyone with a calculator could in theory disprove it. The fact that no one has suggests to me that it’s likely true.
