I came to a similar conclusion years ago. Yes, there are examples of applications that have done it, but they often have very elite engineers. Most teams are comprised of various levels of engineers and its extremely difficult to get right.

I work more in web dev now and I suspect the majority of my team does not know the difference between a thread and a process. HN readers may scoff but these are productive engineers who have build some honestly pretty impressive apps and systems.
