Fearmongering? That's a strange choice of words.

> Do you have profiler data showing that the microseconds needed to pass a message between a process is a significant limiting factor

What? I think you didn't get my point. Let me try again.

You can look at a single operation and say "oh, that's nothing, it's so cheap, it only takes a millisecond". Even though there's a way to do the same thing that takes much less time.

So this kind of measurement gives you a rational to do things the "wrong" way or shall we saw the "slow" way because you deem it insignificant.

Now imagine that everything the computer is built that way.

Layers upon layers of abstractions.

Each layer made thousands of decisions with the same mindset.

The mindset of sacrificing performance because "well it's easier for me this way".

And it's exactly because of this mindset.

Now you have a super computer that's doing busy work all the time. You think every program on your machine would start instantly because the hardware is so advanced, but nothing acts this way. Everything is still slow.

This is not really fear mongering, this is basically the state of software today. _Most_ software runs very slow, without actually doing that much.
