I think ultimately we need to move away from CAPTCHAs and toward something like a "proof of work" which still makes spamming/botting infeasible, but doesn't require a lot (or any) thought from a human. There are still very important aspects of this to solve (I don't want every website draining my mobile battery doing constant proof-of-work calculations every pageload), but with ML getting better and better and the ultimate goal of passing a touring test being in the interest of multiple unrelated groups, it's only a matter of time before CAPTCHAs are mostly worthless.
