Right now, there are many people on this forum who work for individuals they've never met in the flesh. Reasonable simulation of emails, phone calls, and Zoom meetings are what an AGI needs to deceive the humans, not a dozen mechs lurching about a fortress of crystalline computer chips. You wouldn't know, and if you did know, where would you go for the off switch?

And remember, by the time you've caught on, a bunch of custom blades have arrived at a co-lo, with someone dispatched to install them. Everyone loves a side gig, and hooking up these blades is great.

A reasonably deceptive AGI would pursue a strategy like that as just one tine in a fork. Then there's the botnets, the poorly-secured printers, and there's firmware to corrupt!
