If you can’t hold on to them once they have experience, that’s a you problem.

I work at a large multi-national corp with competitive salaries, benefits, excellent working conditions, advancement opportunities, etc. I still have watched promising junior engineers hit the door just when they were starting to be truly valuable contributors.

you can have a shitty AI that will never grow beyond a ‘new hire.’

So, my perspective on this is that : over the past 12 months, AI has advanced more quickly than all the interns and new hires I have worked with over the past 3 decades. It may plateau here in a few months, even if it does it’s already better than half of the 2 year experienced software engineers I have worked with, at least at writing code based on natural language specs provided to it.

The future problem, though, is that without the experience of being a junior dev, where do you think senior devs come from?

And I absolutely agree, the junior dev pipeline needs to stay full, because writing code is less than half of the job. Knowing what code needs writing is a huge part of it, crafting implementable and testable requirements, learning the business and what is important to the business, that has always been more than half of my job when I had the title “Software Engineer”.

the world suffocated under the energy requirements of doing everything poorly.

While I sympathize, the energy argument is a pretty big red herring. What’s the energy cost of a human software engineer? They have a home that has to be built, maintained, powered, etc. Same for their transportation which is often a privately owned automobile, driving on roads that have to be built and maintained. They have to eat, they need air conditioning, medical care, dental care, clothes, they have children who need to spend 20 years in school, they take vacations on cruise ships or involving trans-oceanic jet travel… add up all that energy and divide it by their productive output writing code for their work… if AI starts helping them write that code even 2x faster, the energy consumed by AI is going to be trivial compared to the energy consumed by the software engineer per unit of code produced, even if producing code is only 20% of their total job.

I would say the same goes for Doctors, Teachers, Politicians, etc. AI is not going to replace 100% of any job, but it may be dramatically accelerating 30% or more of many of them, and that increase in productivity / efficiency / accuracy is going to pay off in terms of fewer ProfessionX required to meet demands and/or ProfessionX simply serving the world better than they used to.

My sister in law was a medical transcriptionist - made good money, for a while. Then doctors replaced her with automatic transcriptionists, essentially the doctors quit outsourcing their typing work to humans and started trusting machines to do it for them. All in all, the doctors are actually doing more work now than they did before when they had human transcriptionists they could trust, because now they are have the AI transcription that they need to check more closely for mistakes than they did their human transcriptionists, but the cost differential is just too big to ignore. That’s a job that was “eliminated” by automation, at least 90% or more in the last 20 years. But, it was really a “doctor accessory” job, we still have doctors, even though they are using AI assistants now…
