Interesting. I see people making overlay-broad claims without evidence or justification.

> I deal as DevOps/SRE daily with these services, and finding one that will do a first load under 10s is close to impossible

Nobody is going to call in for your help unless something is wrong, so don't be surprised you haven't seen anything right. That just means people are keeping the good stuff secret (and/or they don't work for your company)

> I can't help but think these are people heavily relying on React and missing the overall issue.

That's too bad.

I think that everyone who works on a slow project knows it's ultimately Management's fault, and when a codebase gets so big that nobody feels like they can fix it anymore, that's Management's fault too.

Maybe you can think if Management called you in earlier you could've designed a better thing, but guess what: I think that would be Management's fault too.

> but I can at least root for them

Can you imagine if any of what you said was really True, everybody believed you, and everybody actually stopped using these "huge frameworks [that] have made the web a horrible slow mess", and that actually solved "the overall issue" so that all software is perfect and reliable? What exactly do you think a SRE does in this case? Do you think that's even a job?

I really suggest trying to look at things differently, because I think for your skills there's a huge opportunity sitting right in front of you if you can see it.
