Have you looked in detail at the economics of this?
Career finance professionals are calling it a bubble, not due to their suddenly found deep technological expertise, but because public cos like FAANG et. al are engaging in typical bubble like behavior: Shifting capex away from their balance sheets into SPACs co-financed by private equity.
This is not a consumer debt bubble, it's gonna be a private market bubble.
But as all bubbles go, someones gonna be left holding the bag with society covering for the fallout.
It'll be a rate hike, it'll be some Fortune X00 enterprises cutting their non-ROI-AI-bleed or it'll be an AI-fanboy like Oracle over-leveraging themselves and then watching their credit default swaps going "Boom!" leading to a financing cut off.
