If it's worth anything: I have a PhD in (theoretical) mathematics and I entirely stand by stabbles' comment.
There is a real, undeniable possibility of AI becoming better at mathematics in the same way that it became better at chess and Go, and in such a scenario, one may expect the community's response to be comparable.
Stockfish isn't owned by a club of three trillionaires. It does not cost $15 million to achieve a result in Stockfish.
Stockfish does not steal research or scoop researchers.
The concentration of computing resources and capital should be examined by the math community.
It makes no sense to compare mathematics with chess. Chess is a sport. No one is interested in watching two machines compete. Chess doesn't have a practical impact. Etc. What you seem to suggest is that AI will be able to completely (or at least in a great part) replace mathematicians. It could be the case in the future, but no one knows right now, and more importantly: tech companies don't even think about it! they don't think on the externalities.
