I was at Intel for a while and there was one glaring problem - they have one product that spins off a huge amount of cash. This means a few things: First, that one product is really where the things that matter happen. But second, they have all this money and they don't know what to do with it, they can't spend it all on their core product because that looks terrible - they're already throwing off money, investing more probably just makes your company look bad (you're spending more to get the same revenue). SO instead you have to take that money and make bets. But not just any bets. You need a bet that (a) matters if it pays off, and (b) looks favourable compared to the core business. So you buy Mcafee and Altera and MobilEye, 5G was the future once...

So to take the Meta example, they need something that is going to have revenue upside similar to Meta advertising revenue (one of the most profitable things in the universe), and that has better margins that the advertising business (basically impossible).So the only logical thing to do is to make grotesquely large bets on things that are extremely speculative. You can't bet on things that are well known - because nothing known has the properties from earlier that you're looking for, and you can't bet small because you've got to convince people you're the pay off is of a similar size to your existing business.

In Intel's case they lost focus on the core business and so that died and their other bets didn't matter because the core business was dead. With Meta the core business in't dead, but it's only a matter of time before it's seriously threatened and so they're going to attack that threat with everything they've got - and they have a tonne of resources.
