Why is this never going out of fashion: https://en.wikipedia.org/wiki/...

You're thinking of PCP.

Last time I did PHP was in 2007. JS is so powerful now that it's all I need for webdev.

Physics will always win.

In my job I spend a lot of time convincing companies that they can save a lot of money on improving software performance. However, they all seem very reluctant to even go there. It is really weird because it has all the upsides and none of the downsides, and it doesn't take that much of an effort either based on the prior work I have done and the systems they show me that are in need of improvements. Recently one of them posted major losses because of a "mismatch" between customer needs and runrate or something, but I know that they are paying >$10K monthly for bloatware and "LLMs" that cannot scale. I wish I could convince them otherwise, but since they are stupid it's a waste of my time.

I had to fight my insurer for months just to get the bare minimum when I had a waterleak caused by the flat above me. They were so dismissive and annoyed with me contacting them I felt like they hated me simply for existing. All their excuses for their slow negligence also didn't hold up. The narcissism is real.

It's not about the real profit, but the potential.

Everything is getting dumber as upper level management continues to cling to their positions of power, completely unaware of their impact, for as long as they can. This is why "LLMs" and diffusion models (which are a red herring) can become useful, when the baseline is someone who never faces consequences.

The lack of awareness these days is astounding. It's like something in the water, vaccines, air, food, etc. is just turning a lot of people into narcissists.

"LLMs" are a red herring. Physics will always win.

Consequences for thee, but not for me.

...and only make it harder for those who are there legally.

Squiiiiiiiiiiiiiiiiiiiiiiiish

And (also, but not limited to) why?

You can't denoise noise without the ground truth. Physics will always win.
