I am a very recent joiner and it’s new to me (I did not however downvote). What is that about?

Because software allows you to turn it on remote or automatically according to some logic (scheduling, presence detection etc.) rather than having to manually connect a circuit at a predefined physical location.

That argument does make some sense but of course he’s making it purely out of self-interest. It would be interesting to have some kind of open-source distributed system where you can share your compute when you’re not using it. But that’s not what he’s proposing.
