AI useful, but warning bells grow amid illusion of overheated investment

Criticism is growing that overheated expectations and an investment frenzy around AI rely more on belief and narrative than technological reality. Cleantechnica ran a column linking the AI bubble with bitcoin and the spread of conspiracy theories, describing “magical thinking” in modern society. It cited expectations of quick riches and visions of near-term abundance. The Wall Street Journal also pointed to unusually high ADR premiums as another warning sign of overheated AI investment.

Edelsten said Micron’s past buy points coincided with negative expected earnings, while apparently low P/E periods marked sell points. He flagged oversupply concerns, SK hynix’s $28 billion ADR fundraising for new capacity, and said markets await clearer evidence that AI revenues can cover heavy investment costs.
