Yeah, and I'm sure whatever third hand gossip you heard is so much more valid.
I forget the guy's name, but they had a real computer expert that scoffed at the idea.
And yes, Elon Musk (who came to prominence by co-founding and selling a web based company in the mid 90s) and Neil Degrasse Tyson (who is an astrophysicist, so computers are definitely not his expertise) say such things but are not experts in those fields by any means. Real experts who majored and work in those fields say that both the idea of us living in a simulation is slim to none and robots taking over the planet is slim to none.
