Some engineers on my team at Assembled and I have been a part of the alpha test of Codex, and I'll say it's been quite impressive.

We’ve long used local agents like Cursor and Claude Code, so we didn’t expect too much. But Codex shines in a few areas:

Parallel task execution: You can batch dozens of small edits (refactors, tests, boilerplate) and run them concurrently without context juggling. It's super nice to run a bunch of tasks at the same time (something that's really hard to do in Cursor, Cline, etc.)

It kind of feels like a junior engineer on steroids, you just need to point it at a file or function, specify the change, and it scaffolds out most of a PR. You still need to do a lot of work to get it production ready, but it's as if you have an infinite number of junior engineers at your disposal now all working on different things.

Model quality is good, but hard to say it's that much better than other models. In side-by-side tests with Cursor + Gemini 2.5-pro, naming, style and logic are relatively indistinguishable, so quality meets our bar but doesn’t yet exceed it.

If you aren't hiring junior engineers to do these kinds of things, where do you think the senior engineers you need in the future will come from?

My kid recently graduated from a very good school with a degree in computer science and what she's told me about the job market is scary. It seems that, relatively speaking, there's a lot of postings for senior engineers and very little for new grads.

My employer has hired recently and the flood of resumes after posting for a relatively low level position was nuts. There was just no hope of giving each candidate a fair chance and that really sucks.

My kid's classmates who did find work did it mostly through personal connections.

This may be unpopular/counter-intuitive to say, but in a capitalist world this is probably the best outcome IF (and I'm not saying I can predict the future) we expect the profession to die/be obsolete from a society POV - in such a world restricting juniors before they commit a whole career to that profession and invest too much resources into it is actually the outcome we probably want. Better than the alternative of even more mass unemployment later. If that's the case then giving people that info early, and avoiding more hiring/training now stops potential mal-investment of money and people's time into training/hiring/building careers in/etc.

It stops juniors investing their life/time/energy in a field that is shrinking and that will increasingly "not be worth it" w.r.t effort put in given their longer time horizon. This is how capitalism when working correctly can obsolete jobs somewhat charitably - it does it by closing the door on entry level jobs ideally when people have little to lose and haven't yet invested a lot of their life into it. For example they may still be young enough to re-train; or may be dismayed from entering the field due to disruption/chatter and so do something more appropriate in the new world.

Being hired in a sinking and increasingly more competitive field may actually be considered a "winner's curse" outcome, in that you will be in a industry highly competitive that is slowly sinking and is stressful with low opportunities for pay rises compared to other industries/skill sets - this is definitely playing your career in "hard mode". Most of all you will feel your skills, and value is useless relatively to people who got into more jobs with more scarcity playing life in "easy mode" with less stress and anxiety. In a few years time people getting into other fields may feel they "dodged a bullet" comparing themselves to others that did.

Being able to pivot while you are still young and ageism isn't a barrier yet is definitely something to consider remembering careers these days are multi-decades long. I feel for your kid now, and I do for mine, but I would rather than try something different in their 20's vs say their 40's when they have a mortgage, a family to feed, and/or other commitments and ageism makes it harder to pivot/re-train into another career. I don't wish my kids to feel the anxiety I and many people I know are feeling later in life especially for a career that requires constant effort to maintain and keep relevant in. I'm not recommending my kids learn what I do at all for example.
