One of the questions from https://jacyanthis.com/big-questions.

Resolves according to my judgement of whether the criteria have been met, taking into account clarifications from @JacyAnthis, who made those predictions. (The goal is that they'd feel comfortable betting to their credance in this market, so I want the resolution criteria to match their intention.)

Clarification:

Conditional on no AGI or population collapse.

Because of the likely transformative nature of AGI and superintelligence, I phrase many of my predictions about the future as conditional on no AGI so that the predictions are less dependent on AGI timeline estimates. I would estimate above 90% that technologies like cultured meat, fusion, and life extension will be developed very quickly after superintelligence. Similarly, I condition on no population collapse because I would estimate under 10% that these technologies would develop after population collapse to below, say, 1 billion humans (e.g., nuclear winter, pandemic) without decades of recovery time.

Get Ṁ200 play money
Sort by:

It's probably possible with D-T, but T is so expensive and you get much more energy from breeding fissile isotopes from U238 or Th232 than breeding T from D, so doubtful it will ever be economically viable. D-He3 is probably not possible to even reach Q=1.

bought Ṁ200 of YES

You don't breed T from D. You breed it from lithium.

Li6 + n -> H3 + He4 + 4.8MeV

bought Ṁ5 of YES

I'd be shocked if this doesn't happen tbh. >90%.
