Its also super clear that this is a technology that most of Big Tech totally missed and seems unable to catch up on (Apple, Amazon, Microsoft; Google is doing fine). There's a seriously possible Microsoft-vs-IBM-v2 play possible in the next couple years.
I'm a cynic, but I'm not convinced this is a bubble in the traditional sense. I'd argue that its startlingly asinine to point at a product that went from nothing to being used by 10% of the planetary population in two years, accidentally, like they internally thought it was a stupid idea and still think its a stupid idea, and say "nah they got nothing".
