There is unprecedented capital expenditure ($50B–$100B) flowing into hardware, data centers, and energy. While the AI trend is real, the current build-out creates a risk of "overbuilding." The market is pricing in perfection, but physical constraints (energy) and ROI questions remain. The sheer volume of capital chasing hardware, combined with "circular" funding deals in the AI startup ecosystem, mirrors the pre-crash vibes of 2000. If AI adoption accelerates faster than hardware supply, these stocks will continue to run despite valuation concerns.
