Was it really the internet that killed third places?
Among all candidates, it seems the least likely here. It didn't even happen at the same speed the internet grew.
(The issues with monopolized editorial powers are still valid, it's just this one that I think is wrong.)
Say more?

Overwork, lack of space, lack of transportation.
I imagine people blames the internet for lack of interest (as in "social networks are a dopamine machine"). But IMO it's absurd to jump into a lack of interest when the physical means for people to get together are destroyed.
