"Microsoft has poured over $13 billion into the AI firm since 2019..." My understanding is that this isn't really true, as most of those "dollars" were actually Azure credits. I'm not saying those are free (for Microsoft), but they're a lot cheaper than the price tag suggests. Companies that give away coupons or free gift certificates do bear a cost, but not a cost equivalent to the number on them, especially if they have spare capacity.
