Not convincing. This post:

* Aggregates disparate devices (e.g. PC, smartphone and watch)

* Mentions functional units which could theoretically be treated like a computer (e.g. Turing-complete) - but aren't a computer which acts independently.

* Counts cores as different computers, but - either a core is a computer, or the system with multiple cores is a computer. The computation a multi-core system does is having one of its cores run.

So basically, you'll be told about the on-Mobo chip for controlling its operations, and the Intel Management Engine and the AMD equivalent. Not worth the read IMHO.
