The FT article isn't as doom-laden as either of you are suggesting - 300tn of additional investment requires raising the investment budget by 50%, and in due course (although this is only pointed out in the comments) some of that capital investment will be offset by revenue savings (see the Tesla thread for examples). Global GDP is set to be 29tn pa larger in 2026 than this year - let's not be defeatist. On the other hand, the article is right to flag that getting people to pay for the changes is likely a bigger challenge than establishing the technology itself.
