Huh? Servers take loads-of-cores as far as you possibly can! Zen2
parts announced the other day, they'll give our servers something like
256 threads!

Even embedded parts have many cores; look at every mobile processor.
But here's the best part; if you design your software to run well on
computers... it does!
Multi-core focused software tends to perform better on single-core
setups than software that was written for single-core in my
experience.
My most surprising example was when we rebooted our engine in 2005 for
XBox360 and PS3 because we needed to fill 6-8 cores with work and our
PS2 era architecture did not do that effectively. At the time, we
worried about how the super-scalar choices we were making would affect
Gamecube which still had just one core. It was a minor platform so we
thought we'd just wear the loss to minimise tech baggage... boy were
we wrong! Right out of the gate, our scalability-focused architecture
ran better on the single-core machines than the previous highly mature
code that had received years of optimisation. It looked like there
were more moving parts in the architecture, but it still ran
meaningfully faster.
The key reason was proper partitioning of work. If you write a
single-threaded app, you are almost 100% guaranteed to blatantly
disregard software engineering in favour of a laser focus on your API
and user experience, and you will write bad software as a result.
Every time.
