David Woo warned that sky-high AI valuations rest on "winner-take-all" dynamics and "fear of missing out"-driven disorderly capital spending, lacking natural moats and underlying economic logic. He questioned whether accounting depreciation and investment returns at some giants are masking profits. He has temporarily stepped back tactically to observe, stressing that if the AI narrative collapses, it would deliver a catastrophic blow to US stocks.
