Human nature?
In the early nineties, it was common for experienced electrical engineers to keep on using schematic entry digital design and look down on RTL and synthesis tools, despite that fact the latter was already way more productive. At some point, management had to put their foot down and force everyone to switch to using synthesis.
It's not unreasonable to assume that many people are set in their ways and unwilling to change their behavior without a bit of a push.
It is completely unreasonable to assume that. Tech people are so hungry for productivity gains that they regularly will defy management forbidding them from using a tool, because the tool is so good they feel they have to have it.
If LLMs truly are as good as their proponents say, engineers will use them even if management outright forbade it. The fact that people aren't using them, and have to be forced, is extremely strong evidence that they are not in fact that useful.

Surely you can't argue in good faith today that LLMs aren't useful? It was a valid argument a year ago, but the latest models are absolutely useful at solving whole classes of problems.
They're not perfect, need to be carefully monitored, can cause weird gambling like dopamine rushes and can cause lazy development habits to creep in. But none of those things negate the fact that, in many situations, they are useful.
Useful = net benefit.
Short-term, sure in some contexts. Long-term? Nobody knows yet.

See my other reply in this subthread. For my line of work, they are in fact ridiculously useful.
Alpha 21064, 1992, was using domino logic [1].
[1] https://en.wikipedia.org/wiki/Domino_logic
There was no synthesis algorithms that would map VHDL or Verilog designs into domino logic elements at the time. I believe that the most work in the synthesis-to-domino-logic area was done at the beginning of current century.
So, DEC's engineers and, I think, Intel's engineers were doing work using schematics well into 21-st century.
In the early nineties, standard cell design was already used by everyone except those who needed clock speed at all cost.
I guess the only difference between this and your example is the concrete efficiency gain from RTL and synthesis tools versus dubious applications of AI. I do agree with the second point about pushing people to explore new ways of doing things though.
> dubious applications of AI
Leaving aside the ethical aspects of using AI (not because they're not valid, because they're off topic for this discussion), in my line of work, the capabilities and productivity improvement of AI are staggering. Most of it is not writing the new code, which is but a small part of chip design, but everything else.
I can't give a concrete work example, but here is an experiment that I ran a month ago. https://tomverbeure.github.io/2026/04/12/AMIQ-License-Key-Ge.... If it can do that, it's not hard to imaging similar use cases related to root causing complex simulation failures. It is frighteningly good at that.
Fair points! Thanks for sharing the write-up as well - great read.
> use cases related to root causing complex simulation failures.
That's a pretty interesting use case. I assume this is for RTL simulation given the thread, but how do you connect the output of the simulator to the AI?

You include those only in second round along with guidelines and recommendations on how to use it effectively.
What if those people are some of the most experienced ones, who can see use cases, and flaws, that more junior people won't?
People who have to be forced to try it are unsuitable for the exploratory "find what it is useful for" task regardless of seniority.
Also, we are talking about large companies here. There will be plenty of more suitable seniors.
