> What happens when there are no more entry-level humans to be promoted to mid-level, and so on?
No business cares about that question, just like the Onceler didn't care how many Truffula trees were left. It's not their problem. Business is business, and business must grow, regardless of crummies in tummies, you know.
It even has a name, tragedy of the commons. I have been saying it constantly for the last few years with all this AI hype over LLM's going on. But with business focus really narrowing down to short time frames, what do you expect
The "business" doesn't care about this, but individual employees care about their job duties, not their business. And some of them do have a job duty where they care about this.
(i.e. this cynical complaint is exactly the opposite of the cynical complaint about managers/directors engaging in empire building.)
Well looked at what has always happened in society when young people have no hope for the future: massive societal disruption mostly in the forms of revolution + violence.
Since this isn't the 1800s anymore there won't be any major revolutions but I expect way more societal violence going forward. If you have no hope for the future it's not hard to go to very dark paths quickly, usually through no fault of your own sadly.
Now add how easy it is for malicious actors to get an audience and how LLM tech makes this even easier to do. Nice recipe for a powder keg.
