Thanks. We'll look at and fix what's off.
“if you aspire to do true work, your probability of success is much higher.”
Elon Muskat 22:43 · Lightcone22:43Takeaways
- Judge a product by how useful it could be, and to how many.
- Internalize responsibility and keep ego from breaking the feedback loop.
- Do the task at hand, whether it is grand or humble.

What would you tell to the Elon who's never had to do that yet? I generally think to try to be as useful as possible. It may sound trite, but it's so hard to be useful, especially to be useful to a lot of people. Where you say the area under the curve of total utility is like, how useful have you been to your fellow human beings times how many people? It's almost like the physics definition of true work.
- 22:54
It's incredibly difficult to do that. And I think if you aspire to do true work, your probability of success is much higher. Like don't aspire to glory, aspire to work. How can you tell that it's true work? Like, is it external? Is it like, what happens with other people or what the product does for people? Like what is that for you? When you're looking for people to come work for you, like what's the salient thing that you look for?
- 23:22
Or if there are a few. That's a good question, I guess. I mean, in terms of your end product, you just have to say like, well, if this thing is successful, how useful will it be to how many people? and um that that's that's what i mean and and then you do you do whatever you know whether you're a ceo or any role in a startup you do whatever it takes to succeed like and just and just always be smash smashing your ego like like internalize responsibility um like a major failure mode is when uh ego to ability ratio um is double greater than sign one you know So...
- 24:00
Like, if your ego to ability ratio gets too high, then you're going to basically break the feedback loop to reality. And in AI terms, you'll break your RL loop. So you don't want to break your RL. You want to have a strong RL loop, which means internalizing responsibility and minimizing ego. And you do whatever the task is, no matter whether it's grand or humble. so i mean that's kind of like why actually i prefer the term like engineering as opposed to research i prefer the term and i don't i actually don't want it to call xai a lab i just want to be a company um i like it's like whatever the one of the simplest um most straightforward uh ideally lowest ego terms are those are generally a good way to go um So you want to just close the loop on reality hard.

That's a super big deal. I think everyone in this room really looks up to everything you've done around being sort of a paragon of first principles and thinking about the stuff you've done.
