I would like to ask about the classification of finite simple groups, in particular, how we can be confident that it is correct. This post asks essentially the same question, so if I were to ask, it would presumably be flagged as a duplicate.
However, the accepted answer does nothing more than state 'yes, we can be confident', and links a short article which overviews the status of the proof, and outlines it a bit. As far as I can tell this does nothing to answer the question besides that the author also states that they are confident the CFSG is correct, and that the 2nd and 3rd generation proofs are being done for clarity, not because of doubts over their proof.
The comments also provide links to two MathOverflow questions. This one gives updates on the status of the second generation CFSG. This one asks if there is an intuitive reason to expect something like CFSG to be true, and the answer is broadly 'no'. So neither do anything to suggest we should have more confidence in CFSG.
What can I do to get an answer to this question?
