I - senior - can patch an application in an unknown language and framework with the AI. I know enough to tell it to stop the wildly stupid ideas.

But I don't learn. That's not what I'm trying to do- I'm trying to fix the bug. Hmm.

I'm pretty sure AI is going to lead us to a deskilling crash.

Food for thought.

For an experienced engineer, working out the syntax, APIs, type issues, understanding errors, etc is the easy part of the job. Larger picture issues are the real task. But for many Jr engineers it’s the hard part. They are not (yet) expected to be responsible for the larger issues.

what is a larger issue ? lacking domain knowledge? or lacking deeper understanding of years of shit in the codebase that seniors may have better understanding? where I work, there is no issue that it "too large" for a junior to take on, it is the only way that "junior" becomes "non-junior" - by doing, not by delegating to so-called seniors (I am one of them)

While I have no particular love for AI generated code, I think this has nothing to do with AI. Software has been unreliable for over a decade. Companies have been rushing out half baked products and performing continual patches for many years. And it's our fault because we have just come to accept it.

> Software has been unreliable for over a decade The "over" deserves a lot of emphasis. To this day, I save my code at least once per line that I type because of the daily (sometimes hourly) full machine crashes I experienced in the 80s and 90s.

Same, I think I should just turn on autosave at this point to save my fingers

"Larger issue" is overall technical direction and architecture, making decisions that don't paint you into a corner, establishing maintainability as a practice, designing work around an organization's structure and habit and so on.

But these are the things people learn through experience and exposure, and I still think AI can help by at least condensing the numerous books out there around technology leadership into some useful summaries.

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?

They have an emacs package that triples their . automatically!

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…

Don’t confuse this with this persons ability to hide their instincts. He is redefining “senior” roles as junior, but words are meaningless in a world of numbers. The $$$ translation is that something that was worth $2 should now be worth $1.

Because that makes the most business sense.

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.

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…

> Even more recently we had this with radiologists, a profession that was supposed to be crushed by deep learning and neural networks. A quick Google search says an average radiologist in the US currently makes between $340,000 to $500,000 per year.

At the end of the day, radiologists are still doctors.

"BUT I see juniors often are the ones who actually understand AI tools better than seniors"

Sorry, what does that mean exactly ? Are you claiming that a junior dev knows how to ask the right prompts better than a Senior dev ?

you're right but my opinion about this has changed

I would have agreed with you 100% one year ago. Basically senior engineers are too complacent to look at AI tools as well as ego driven about it, all while corporate policy disincentivizes them from using anything at all, with maybe a forced Co-Pilot subscription. While junior engineers will take a risk that the corporate monitoring of cloud AI tools isn't that robust.

But now, although many of those organizations are still the same - with more contrived Co-Pilot subscriptions - I think senior engineers are skirting corporate policy too and become more familiar with tools.

I'm also currently in an organization that is a total free for all with as many AI coding and usage tools as necessary to deliver faster. So I could be out of touch already.

Perhaps more complacent firms are the same as they were a year ago.

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 des…

One thing I'd point out is that there are only so many ways to write a document or build a spreadsheet. There are a ton of business processes that are custom enough to that org that they have to decide to go custom, change their process, or deal with the inefficiency of not having a technical solution that accomplishes the goal easily. Lotus Notes is an example of that custom software niche that took off and spawned…

> Lotus Notes is an example

TIL Notes is still a thing. I had thought it was dead and gone some time ago.
