If you have experience and effective training browsing the dark web, there are several examples of your concerns already coming alive.

Bot farms have levelled up to ai farms, with various models being made as ‘specialist’ ai’s for things like credit card theft, network intrusion, malware, etc, and from when I last looked into it a few months ago they had already moved on to attempt to get all the specialists to start training general purpose ai’s.

Things are not looking particularly great and I would posit if AGI does happen in our lifetime it’s not going to be because anyone alive actually intended that to happen, but the criminals running a wide variety of specialists train a general purpose ai with intentions to use it for easy money.

I usually chirp back with ‘nothing we have now is really AI’ but I can’t seriously take that view with some of the things being tested by some criminal organizations these days and there’s not really a way to stop this from happening.
