I’ve been to a few conferences that did things like this (that predates “AI”) and it is actually a REALLY good idea that encourages people who are just there to give a talk or who are socially awkward to actually network.

The key is that it needs to only make suggestions and not actually send calendar invites. And it needs to be opt-in until at least one human says “Yeah, that is a good idea. See if Fred wants to meet some time tomorrow” and only then do the other parties get a push/email asking if they are free.
