I imagine there is a correlation between novel/interesting ideas that generate new revenue and being immersed in an environment of peers that you collaborate/chat with.
However remotely I am basically never off. A common thing that comes up with remote work is you have a hard time just turning off, but I don't mind as I'm not mentally exhausted by interruptions and can actually enjoy the work I'm doing.
But I'm sure its a person to person thing, type of environment, industry, etc.
I think the early 2000s burned a lot of companies for trying to cheap out on dev costs by offshoring - offshoring is a valid choice in some situations and will probably become more and more competitive as time goes on... but there still is quite a lot of value in hiring out of the four year uni grad pool.
