Can't speak for their usage, but I calculated my token use with Copilot, my employer paid 22$ for >2000$ in tokens. Given estimates margins, Github is paying 98-99% of the costs for us.
I imagine Claude max etc is similar. So it's not sustainable at all
Others are pointing out that many also lost money, but I think we can say something even stronger, which is that the people that got rich only did so by taking the money of the people who lost money on it. If it's the future of money, you'll be able to buy in at a stable valuation, neither winning nor losing in the transition -- that's kind of a key property of money.
