The million dollar (perhaps literally) question is – could @kentonv have written this library quicker by himself without any AI help?
But what if you only need 2 kentonv's instead of 20 at the end? Do you assume we'll find enough new tasks that will occupy the other 18? I think that's the question.
And the author is implementing a fairly technical project in this case. How about routine LoB app development?
This is likely where all this will end up. I have doubts that AI will replace all engineers, but I have no doubt in my mind that we'll certainly need a lot less engineers.
A not so dissimilar thing happened in the sysadmin world (my career) when everything transitioned from ClickOps to the cloud & Infrastructure as Code. Infrastructure that needed 10 sysadmins to manage now only needed 1 or 2 infrastructure folks.
The role still exists, but the quantity needed is drastically reduced. The work that I do now by myself would have needed an entire team before AWS/Ansible/Terraform, etc.
But if the time it takes an engineer to build any one thing goes down, now there are a lot more things that are cost effective.
Consider niche use cases. Every company tends to have custom processes and workflows. Think about being an accountant at one company vs. another -- while a lot of the job is the same, there will always be parts that are significantly different. Those bespoke processes often involve manual labor because off-the-shelf accounting software cannot add custom features for every company.
But what if it could? What if an engineer working with AI could knock out customer-specific features 10x as fast as they could in the past. Now it actually makes sense to build those features, to improve the productivity of each company's accounting department.
It's hard to say if demand for engineers will go down or up. I'm not pretending to know for sure. But I can see a possibility that we actually have way more developers in coming years!
That's definitely an interesting area, but I think we'll actually see (maybe) individual employees solving some of these problems on their own without involving IT/the dev team.
We kind of see it already - a lot of these problem spaces are being solved with complex Excel workflows, crappy Access databases, etc. because the team needed their problem solved now, and resources couldn't be given to them.
Maybe AI is the answer to that so that instead of building a house of cards on Excel, these non-tech teams can have something a little more robust.
It's interesting you mentioned accounting, because that's the one department/area I see taking off and running with it the most. They are already the department that's effectively programming already with Excel workflows & DSLs in whatever ERP du jour.
So it doesn't necessarily open up more dev jobs, but maybe fulfills the old the mantra of "everyone will become a programmer." and we see more advanced computing become a commodity thanks to AI - much like everyone can click their way through an office suite with little experience or training, everyone will be able to use AI to automate large chunks of their job or departmental processes.
