| 0:00.0 | Nobody wants intelligence, period. |
| 0:02.0 | I want something else, right? |
| 0:03.0 | And that something else is always specific, or at least more specific. |
| 0:06.0 | There is this kind of observed phenomenon where if you over-engineer intelligence, you regret it because somebody figures out a more general and maybe potentially simpler method that scales better. |
| 0:18.0 | And a lot of the hard-coded decisions you made are things you end up regretting. |
| 0:21.4 | So I think it's fair to assume that like models will get better and algorithms will get better |
| 0:27.0 | and a lot of that stuff will improve. |
| 0:29.6 | Then the question we really ask is intelligence is great, but what problems are you actually trying to solve? |
| 0:33.4 | That idea that scaling model parameters and scaling just pre-training data is all you need, |
| 0:38.2 | exists nowhere anymore. Nobody thinks that. Actually, people deny they ever thought that at this point. |
| 0:42.9 | Now you see this massively human designed and very carefully constructed pipelines for post-training, |
| 0:49.6 | where we really encode a lot of the things we want to do. You see massive emphasis on retrieval |
| 0:53.4 | and web search and tool use and agent training. |
| 0:56.0 | There is clearly a sense in which the labs have already recognized that the old playbook doesn't work. |
| 1:01.0 | The question is, is that actually sufficient for making the best use and the most use of these language models? |
| 1:07.0 | It's not a problem of capabilities. |
| 1:09.0 | It's a problem of actually we don't necessarily |
| 1:11.1 | just need models. We want systems. The conventional wisdom says we're racing toward EGI |
| 1:17.0 | by making language models bigger and bigger. But what if the entire framing is wrong? On today's |
| 1:22.1 | episode, you'll hear from A16Z general partner, Martin Casado, and guest Omar Khatav, |
| 1:27.2 | assistant professor at MIT and creator of DS Pi. |
| 1:30.7 | Omar doesn't think we need artificial general intelligence. |
