It's only your opinion that is provably false.
First, there are still people who don't like high level languages and don't use them, because they find assembly better.
Second, I personally work in a field where I need to consult the source of truth, the actual binary, and not the high level source code - precisely because the high level of abstraction is obscuring the real mechanics of software and someone needs to debug and clean up the mess done by "high level thinkers".
High level programming languages are only an illusion (albeit a good one) but good engineers remember that illusion is an illusion.
I can tell you this, the person you're replying to comes from the overwhelming majority/generality. You, on the other hand, are that one guy.
Of course even my comment is a bit general. You're not "one" guy literally. But you are an extreme minority that is small enough such that common English vernacular in software does not refer to you.
Also, if you need to control performance, you still need to know how CPU cache and branch prediction works, both of which exists at the abstraction level of assembly.
And putting aside the vanishing skill, there is also an issue of volume.
All that LLMs and other generative models have done is enable an order of magnitude more stuff to be created cheaply. This then puts the onus and cost on the consumer of that output, hence why everyone is exhausted after a day of work that just involves looking over output. This volume of output will cause people to stop looking at all of the output and just trust the randomly generated code, and in time the quality will suffer.
It's worrying how much trust is being put in those systems. And my worry is not about the job anymore, but our future in general.
So, on one hand, I'm also kinda sad and how quickly we've thrown the guardrails away, but on the other -- it's... Well. It's just work.
Turns out, no one ever really cared how elegant or robust our code was and how clever we were to think up some design or other, or that we had an eye on the future; just that it worked well enough to enable X business process / sale / whatever.
And now we're basically commoditised, even if the quality isn't great, more people can solve these problems. So, being honest, I think a lot of my pushback is just a kinda internal rebellion against admitting that actually, we're not all that special after all.
I'm just glad I got to spend 20 years doing my hobby professionally, got paid really well for it, and often times was forced to solve complicated problems no one else could -- that kept me from boredom.
I think the shift we are seeing now, as 'previously' knowledge workers is that work becomes a lot more like manual labour than what we've really been doing up until now. When there's no 'I don't know' anymore, then you're not really doing knowledge work, right?
I guess I'll just ride the wave, spew out LLM crap at work, and save the craft for some personal projects, I'll certainly have the capacity now work is a no-op.
In a corporate world, we are typically detached from real world consequences and looking at people around me, people really don't think about such things - but I do. And I really care, because "relaxed" standards might result in errors that amount to stuff like identity thefts, or stolen money, shit like this, even on the smallest scale.
Obviously we can't prevent everything, but it seems like we, as industry, decided to collectively YOLO and stop giving shit at all. And personally I don't like that it is me who is losing sleep over this, while people who happily delegate all their thinking over to LLMs sleep better than ever now.
Keep it simple right; in everything you do, make things a bit better than you found them. It's enough. You're never going to win the fight to get everyone (or maybe even ANYONE depending how messed up your org is) to care; so why lose sleep on things you can't change?
At least, that's what I started doing some years ago by now having lost lots of those fights, and I'm sleeping fine again.
Our futures are safe in this sense, in fact it's even beneficial as we may be the last generation to have these skills. Humanities future on the other hand is another open question.
You can learn to understand the patterns that compilers spit out and there are many tools out there to aid in that understanding. You can't learn to understand what an LLM spits out because by design it is non-deterministic and will vary in form and function for each pull of the lever.
You can learn to understand how high level concepts in code map down to assembly language and how compilers transform constructs in one language to another. You can't know that about LLMs because they generate non-deterministic output based on processing of huge low-precision tables.
It's not even a close comparison.
I wonder if this sort of trend will continue?
(A competent assembly programmer can go miles around a competent high-level programmer, that's still true in 2026...)
GenAI is like a non-deterministic compiler. Just like your manager's reports except with less logical thinking skill. I'd argue this is still problematic.
