AI Doom Debate Flares Up Over the "Short the Market" Challenge

The dispute over whether AI doomers should put their money where their mouth is kept escalating from October 8–9. VC Mike Solana tweeted questioning doomers' debating tactics: why always spar with writers like Steven Pinker and Claire Lehman, who know little about AI, rather than insiders like Tyler Cowen and Curtis Yarvin. igypham responded that Cowen is worse than Pinker—his only rebuttal to doom arguments has become "so short the market?"—while Pinker at least pretends to engage with the substance.

Confirmed

• csvoss firmly backed the Cowen-style rebuttal, saying "short the market?" is actually a good argument, and he has yet to see a rebuttal that holds up.
• csvoss's core claim: as long as p(doom) isn't exactly 100%, you should still look for and trade arbitrage opportunities today—future events could well pull p(doom) down, and in those worlds money still matters; if you think the market is wrong, arbitrage exists.
• dlbydq countered: if p(doom) is 99%, you'll never get to spend the money you make shorting the market, so the highest-expected-value trade is actually to "go insanely long," using the analogy of "hedging the dollar against the dollar going to zero" to challenge the logic of doomer hedging.

Unconfirmed

• csvoss conceded that dlbydq's rebuttal is strong, saying he hasn't seen a satisfying response yet—the debate remains unresolved.

Why it matters

• The spat puts the gap between "verbal doom concerns" and "betting real money" center stage, offering a market-based test of AI doomers' belief consistency; meanwhile, Solana's critique reflects the controversy over "picking opponents" in doom debates, where serious insider-to-insider exchanges remain scarce.
