Why is the kind of sitcom "30something people living together in a big city" dead now?

"Friends" was the most popular show of this kind. But there were some examples before (Like "Cheers" or "Seinfield") and there were their heirs after ("How I Met Your Mother","Big Bang Theory","New Girl"). But right after those,now its almost a decade that these kind of sitcoms are not produced anymore. The sitcom genre in general is almost disappeared,but specifically this kind of sitcom about 30something people in New York (or some other big city) is basically dead. There was the HIMYM spin-off "How I Met Your Father",thats true,and i think thats the only example we can make in the last few years.
Why do you think this happened?
-Its because of the streaming model?
-Its because modern 30 years old dont find them relatable somehow? (But shows like Friends or How I Met Your Mother still makes great numbers on streaming services)
-Or some other reason?

Why do you think that this kind of sitcom is basically disappeared from tv? Can it come back somehow?
