Not sure what Apple VPs have to do with the tech but yeah, pretty much any core engineer you ask at Apple will tell you this.

Here is a nice article with some info about what memory compression is and how it works: https://arstechnica.com/gadgets/2013/10/os-x-10-9/#page-17

It's been a hard technical problem but is pretty much solved by now since its first debut in 2012-2013.

I've heard good things about how macOS handles memory relative to other operating systems. But Linux and Windows both have memory compression nowadays. So the claim is then not that memory compression makes your RAM twice as effective, but that macOS' memory compression is twice as good as the real and existing memory compression available on other operating systems.

Doesn't such a claim... need stronger evidence?
