I think as core counts increase, in 5-10 years we’ll see operating systems that run solely on a dedicated low power core while the other processes run in tickless mode with a more topology aware scheduler and almost no context switching or core migration.

This is already how game consoles and low latency systems work for the most part.

At that point microservices might become more palatable since the context switching won’t damage the rest of the processes performance as much. And Linux’s performance advantage might dissipate as scheduling and cache pressure become less relevant.
