But you can't get all these things in the browser. You don't just increase CPU frequency and get free performance anymore. You need conscious effort to use GPU computing, conscious effort to ditch current I/O stack for io_uring. Modern hardware gives performance to ones who are willing to fight for it. Disparity between naive approach and optimized approach grows every year.
I'm not arguing against your point at all. I'm just pointing at the fact that there are many who are happy to wait a year, buy a 10-20% faster CPU and call it a day, or buy more/larger instances on the cloud, or do anything but optimize the software they use. Some couldn't even if they wanted, because they buy software rather than develop in-house, and aren't effective in requiring faster performance from their vendors.
