This Math 1.0 followed by Math 2.0 framing is wrong. Mathematics did not start a few decades ago when problem solving became the norm. And it will not end now when problem solving turns out to be "easy".

Mathematics will revert to it's main practice, which is to study.

There are lots of weird panic reactions by some prominent problem solvers. See for example the ridiculous cease and desist like statement of AHM shared at Tao blog.

Put this Math 1-2.0 with that AHM statement together and you'll realize that this is a power struggle and that you see only one side of it.

Mathematicians have very diverse opinions about this. I, for example, am for as much as possible automatic harvesting of all these "low hanging" fruits. Should be disclosed as soon as possible, free of any bottleneck, and citable. The mathematics community may do whatever its various members desire to do with these results. Let them decide individually what to do with them. This AI tool is here to stay.
