The answer is simple: "no".

It's just fundamentally more expensive to send some kind of message than it is to just share the data structures and use the cache coherency.

The only way "IPC" is competitive is if you define IPC as "memory mapping your data structures in shared memory".

We call that "monolithic kernel" exactly because it shares that data address space.

In other words, your whole argument hinges on unreality. In a world that doesn't exist, and no reasonable person expects to exist or even has a realistic plan for, in any kind of reasonable timeframe, your argument simply makes absolutely zero sense at all.

Please make a distinction between reality and your dream world, and just admit it, and stop making arguments that make no sense in other peoples realities, ok?
