AI is a bit like railways in the 19th century: once you train the model (= once you put down the track), actually running the inference (= running your trains) is comparatively cheap.
Even if the companies later go bankrupt and investors lose interest, the trained models are still there (= the rails stay in place).
That was reasonably common in the US: some promising company would get British (and German etc) investors to put up money to lay down tracks. Later the American company would go bust, but the rails stayed in America.
