<br class="">
One of the most popular (and hence hyped) platforms like node.js is<br class="">
single-threaded. And it achieves C10K by doing evented I/O, but if you<br class="">
run CPU intensive tasks, then no event will save you from that.<br class="">
<br class="">
So not everything goes in the multi-threading realm, actually the only<br class="">
thing I see moving in that direction is heavy computation (and to GPU as<br class="">
well).<br class="">
<br class="">
I agree there is no wheel, but up and downs instead, however these days<br class="">
if you take things to extremes the serverless/lambda approach seems to<br class="">
be the most single threaded thing you can think of.<br class="">
