It shows such a lack of understanding of the problem when he says the industry should focusing on saving people time instead of replacing people.
I think he understands the problem just fine. I also think he's smart enough to understand that saying they intend to replace a bunch of people with shell scripts is terrible PR.
Saving workers time so they can be more efficient is what allows companies to cut staff.
That's ONE of the outcomes. The other is that saving worker's time allows them to accomplish more. My company is a small company and we really don't have any workers that we could cut. But we very much could make use of automation that allows our current workers to product more efficiently. Cutting staff is not always the goal. In my company I have a particular type of press I'd love to buy to let us build a product we cannot currently be cost competitive on. I could actually hire more people if I had this press because I could win jobs I'm losing currently.
Saving time and working more efficiently is the whole reason AI threatens jobs.
You could say that about any technology. Most of the hand wringing over AI taking everyone's jobs is the same sort of paranoid response we've had to every technology improvement. We've seen this play before. Back in the 1970s everyone was convinced industrial robots were going to take their jobs tomorrow. Robots did become an important tool but it took decades and most of the displaced workers found new employment in comparatively short order. And plenty of people are still employed on the assembly lines right next to those robots they worried about.
The threat is not that AI will replace all workers (in the short term anyway), the threat is it will increase productivity rapidly enough to replace 20%+ of workers quickly enough that new jobs won't be created fast enough to offset the losses.
While I think your numbers are suspect, this is the only rational argument worthy of concern. There is literally an unlimited amount of work to be done but it takes some amount of time for people to adjust to new economic realities. I think that people are vastly overestimating the risks involved here but fast increases in productivity make for short term dislocations in the work force. Some people have a hard time keeping up.
