Re: If we're talking about actual AI, the number of jobs lost is zero
We have had automation since 1880s and pretty clever stuff by 1930s. You want to see old movies of almost entirely automated valve production (tubes in USA). Not computerised, but automated machines winding the grids, melting and sealing the button base etc.
Anything high volume and repetitive was automated nearly 80 years ago. The difference is than now (apart from ASICs) that production runs can be very small. The FPGA (a mass produced IC) for runs too small for custom chip.
3D printing isn't replacing mass production, and won't, it's making prototyping, mould making, concept work all faster and cheaper.
The last major industry to be much affected by automation was maybe newspaper production? I'm not sure. It's small changes now. It may impact publishing if a bookshop can do in house POD of one copy for $3, but the mass market would still be volume 25 cent per copy printing.
