One of the most popular (and hence hyped) platforms like node.js is
single-threaded. And it achieves C10K by doing evented I/O, but if you
run CPU intensive tasks, then no event will save you from that.

So not everything goes in the multi-threading realm, actually the only
thing I see moving in that direction is heavy computation (and to GPU as
well).

I agree there is no wheel, but up and downs instead, however these days
if you take things to extremes the serverless/lambda approach seems to
be the most single threaded thing you can think of.
