This is exactly how Cloud Computing looked in 2012-2018. Dumping huge $ into computing buildout that wasn't profitable yet. All those co's: Amazon, GCP, Azure paid off immensely and are ridiculously profitable.
No, it wasn't. Cloud computing was almost immediately profitable.
And Amazon was famously "unprofitable" for their first 9 years because they were investing all their very real profits into a form of capital that the US tax code didn't recognize.
You are being downvoted but only a few years ago Google contemplated whether to kill GCP altogether because of lack of traction in the market or revenue goals.
IIRC Amazon chose to reinvest early revenue to grow AWS intentionally, and the revenue curve eventually evened out and obviously surpassed expenses. The problem with the AI buildout is that there's not a ton of evidence that these companies are approaching profitability, we can't even know because they're private.
Amazon's incubation of AWS was methodical and transparent. OpenAI is saying that they don't expect to be profitable until at least 2030, with over a trillion dollars in committed spend before that point. It's the largest "trust me bro" play in human history.
