I can't help but feel this is backpedaling after the AI hype led to people entering university avoiding computer science or those already in changing their major. Ultimately we might end up with a shortage of developers again, which would be amusing.

Agreed.

Considering the talk around junior devs lately on HN, there's way too many of them, it would indeed be amusing.

I have heard this thing quite a few times over last few months each time is Amazon or AWS CEOs. May be this time he want to replace senior engineers. That would be more useful for them as each passing year they more and more of them and in times like these they are not looking to go leave Amazon on their own.

It's backpedaling but I don't think it's planning ahead to prevent a developer shortage - rather it's pandering to the market's increasing skepticism around AI and that ultimately the promised moonshot of AI obsoleting all knowledge work didn't actually arrive (at least not in the near future).

It's similar to all those people who were hyping up blockchain/crypto/NFTs/web3 as the future, and now that it all came to pass they adapted to the next grift (currently it's AI). He is now toning down his messaging in preparation of a cooldown of the AI hype to appear rational and relevant to whatever comes next.

Now with AI, I expect junior developers to learn much quicker and progress to senior very quickly. I'd now rather hire at least 1 of each to begin with, both "junior" and a "senior" developer and then additionally hire more juniors to quickly turn them into a "senior".

We do not need to hire anymore outside senior developers who need to be trained on the codebase with AI, given that the junior developers catch up so quickly they already replaced the need to hire a senior developer.

Therefore replacing them with AI agents was quite premature if not completely silly. In fact it makes more sense to hire far less senior developers and to instead turn juniors directly into senior developers to save lots of money and time to onboard.

Problem solved.

Relevant post by Kent Beck from 12th Dec 2025: The Bet On Juniors Just Got Better https://tidyfirst.substack.com/p/the-bet-on-juniors-just-got... > The juniors working this way compress their ramp dramatically. Tasks that used to take days take hours. Not because the AI does the work, but because the AI collapses the search space. Instead of spending three hours figuring out which API to use, they spend twenty minute…

first response from me "let me mention how the real business world actually works" .. let's add a more nuanced slice to that however

Since desktop computers became popular, there have been thousands of small to mid-size companies that could benefit from software systems.. A thousand thousand "consultants" marched off to their nearest accountant, retailer, small manufacturer or attorney office, to show off the new desktop software and claim ability to make new, custom solutions.

We know now, this did not work out for a lot of small to mid-size business and/or consultants. Few could build a custom database application that is "good enough" .. not for lack of trying.. but pace of platforms, competitive features, stupid attention getting features.. all of that, outpaced small consultants .. the result is giant consolidation of basic Office software, not thousands of small systems custom built for small companies.

What now, in 2025? "junior" devs do what? design and build? no. Cookie-cutter procedures at AWS lock-in services far, far outpace small and interesting designs of software.. Automation of AWS actions is going to be very much in demand.. is that a "junior dev" ? or what?

This is a niche insight and not claiming to be the whole story.. but.. ps- insert your own story with "phones" instead of desktop software for another angle

Well, yeah. Then who will become the senior engineers in 10-15 years?

You think the people deciding whether to hire more juniors are planning more than one or two quarters ahead? 10-15 years is someone else's problem.

Yes, unfortunately 10-15 years is 5 sequential someones else's problems.

Most of the apps that I use regularly fail at least once a day nowadays. I think this is a direct cause of putting AI code in production without reviewing/QA.

My prediction is that this will actually get better, because the cost to find and fix with AI is so much lower in time investment.

Re: AWS CEO says replacing junior devs with AI is 'one of the dumbest ideas'

Interesting take... I'm seeing a pattern... People think AI can do it all... BUT I see juniors often are the ones who actually understand AI tools better than seniors... That's what AWS CEO points out... He said juniors are usually the most experienced with AI tools, so cutting them makes no sense... He also mentioned they are usually the least expensive, so there's little cost saving... AND he warned that without a…

Sorry but what the heck is up with all the ellipses in this comment?

I went to university 2005-2008 and I was advised by many people at the time to not go into computer science. The reasoning was that outsourced software developers in low-cost regions like India and SEA would destroy salaries, and software developers should not expect to make more than $50k/year due to the competition. Even more recently we had this with radiologists, a profession that was supposed to be crushed by de…

Yup hearing big talk about competition and doom is a strong signal that there is plenty of demand.

You can either bet on the new unproven thing claiming to change things overnight, or just do the existing thing that's working right now. Even if the new thing succeeds, an overnight success is even more unrealistic. The insight you gain in the meantime is valuable for you to take advantage of what that change brings. You win either way.
