Epic has too much money and IDK if Tim Cooks plays in the same league with and once Jobs, Sweeney and Huateng. Plus Zuck who just got started. I wouldn't want to be in a war with them together.
Tim is not dumb, not at all but he just maintained one of the industry's strongest network effect/lock-in, not more. Beyond M1 there is not a lot that is not from Jobs' inheritance. Ah yes, broken keyboards for more than three years.
