That's tech... Moore Law was steadily going until raw CPU got stuck for a few years, switching from single core to multicore then heterogeneous cpus, all those requiring to rewrite software in a scalable manner and then consider newer schedulers switching between performance/efficiency cores and changing CPU freqs.

Also, you have Meta and Google investing in simplified performant versions of their stack for developing countries which is similar.

What's funny though, I see people that sometimes says it's cheaper to build the app they need in a single prompt than to search for it.

You know that Moore's law is about transistor count? What worked really well for CPU in eg the 1990s was Dennard scaling. That drove the Hz higher. And Dennard scaling is what stopped working.

Moore's law is alive and well.
