It’s the same sort of juvenile thinking that causes someone to look at a vast legacy codebase and decide “oh we could easily rewrite that.” The reality is that automation is progressing as fast as technology allows, but technology just doesn’t work that well. In fast food, for example, self-order touch screens are vastly inferior to a trained order taker. There are no machines to roll a burrito. There’s no machines to wipe tables, clean bathrooms, clean the kitchen, or even take drive through orders. We don’t, get, have automated ubers, taxis, freight trucks, etc. Grocery checkout automation is atrocious, which is why higher end chains like Whole Foods don’t have them, even though they’re better able to afford automation.
There’s not a single job I can think of that qualifies as a “bullshit job.”
