Total addressable market doesn't pay interest expenses. Even if this technology really did have the potential to be as revolutionary as the move from the horse to the car, if you can't get there with what the world economy's liquidity can provide then you can't get there. Free cash flow is drying up and data centers depreciate. This creates a limit and if that limit is hit before the profit starts coming in it doesn't matter what the potential could be. Paying back interest is financial gravity and it exists today. And this isn't an appeal to Wall Street's short term profit motive, there just is an economic limit to what the capital markets can spend on a bet this big and this risky.
