I feel like the big takeaway here isn't what's covered or not covered, but the percentages.

We have 3 companies claiming something like a $35T market for their services. The world's entire GDP is something like $126T. So 10% of the productive work that is done on this planet, that AI can actually perform makes up fully 1/4 of the entire world's economic output? best guesses for output solely of tech companies is something like $12T. Where are they getting these figures?
