      progress towards AGI would be reflected in making progress on open-ended domains, eg transferring between video games with different skins but common logic. alas the fact that people are working hard doesn’t mean they progress is being made (cf alchemy).https://twitter.com/zergylord/status/997915182075662336 …

      Methodically, I understand what you think the best next steps are. My confusion is about evaluation. No approach currently masters huge open ended domains. If making progress on limited domains doesn't count as progress, then what does?

      > transferring between video games with different skins but common logic We can't do this now? That's surprising to me! (as a non-practicing observer of AI/ML research)

      We indeed can't do this automatically. To clarify, one system could learn either, but having learned one doesn't help it at the other. What led you to think we could?

      Have I misinterpreted this result? https://www.technologyreview.com/the-download/610244/deepminds-latest-ai-transfers-its-learning-to-new-tasks/ … I would have thought that transfer would be even better from the same game with a different skin.

      In general I just would have thought that if you switched skins, then if you started with a neural net trained from pixels, all that would need to change would be the first few layers.

      perhaps a poor choice of words. didn’t mean skins that are pixel for pixel identical; i meant more like the difference between different shooter games set in different environment eg space aliens vs zombies
