I understand training is still costly, but it's not unimaginable for it to turn profitable as well if you think believe they'll generate trillions in value by eliminating millions of jobs.
If you eliminate ONE job and let's say the job pays $100K, in theory at most $100K goes instead to AI revenue. In practice it's a lot less, nobody is going to move everything to AI if it's just a 10% saving.
So, to get a trillion in value, you'd have to eliminate many tens or even hundreds of millions of jobs.
I don't believe this has been the case or claim at all. At best they have recognized some limited use cases in certain models where API tokens have generated a gross profit.
