Yes, and juniors aren't known for their productive work in the beginning. That's not their purpose. Their purpose is to do the mundane work, because it is important for them to become less junior and more senior.
That is robbed of them.
Which in 5-10 years means the need for senior developers is gonna shoot through the roof.
If senior engineers are even 2x more productive with AI, then it’s like there are 2x as many senior engineers.
Most likely, seniors will be 10x more productive in 5 years using AI. This outpaces the retirement rate.
All the software engineers we need for the next 20-30 years are already in the current workforce.
Only way juniors can rise to the level of seniors will be through independent projects, long unpaid internships/apprenticeships, etc.
The industry will now have heavy gatekeeping built in.
There's no way of knowing what the industry will look like decades from now. Even assuming the prediction that seniors become 10x more productive, that would mean software becomes much cheaper to produce. Does that induce enough demand for additional software that keeps employment levels high? Could be, who knows.
Alternatively, maybe software hits a saturation point where there just isn't as much new ground to cover and employment levels crater. That could happen too.
Not even chess-playing? More applicable to jobs though, they're arguably better than some juniors.
A year ago I had no use for any LLM-driven tools, and today I can do my entire job without writing a single line of code.
If that happened in a year, what can we expect in 5? I have no idea what my job might even look like by then.
