Since I am the cofounder of a mostly manual based testing in that space we do follow the new AI hackbots closely. There is a lot of money being raised (Horizon3 at 100M, Xbow at 87M, Mindfort will probably soon raise).

The future is definitely a combination of human and bots like anything else, it won't replace the humans just like coding bots won't replace devs. In fact this will allow humans to focus ob the fun/creative hacking instead of the basic/boring tests.

What I am worried about is on the triage/reproduction side, right now it is still mostly manual and it is a hard problem to automate.
