Google's valuation is not based on their AI. Google has a highly profitable ad and cloud business. I don't know why you are putting NVidia in that list. NVidia sells chips and even if AI models become a commodity they need to run on something. Grok - no ones is valuing it at anything close to 1T. Closer to 100M if anything if you add Cursor. SpaceX valuation is based on their highly profitable Starlink business, highly profitable datacenter build-up and options to charge more for their monopoly in launch. Grok/XAI/Twitter are a small drop in all of it.

Demand for AI is real and increasing. There is real shortage of compute right now. It might be that AI lab is not a sustainable business but I don't see how all that demand evaporates. If anything it will only increase as AI becomes good at more and more tasks.
