Steadily growing every day! More and more people keep finding particle-1 great to use due to token efficiency.
Particle has so many similarities to Mixpanel (scaling events vs tokens). Sometimes it’s like de ja vu. I’ll often feel like I had already gone through a problem before. Since I’ve had a lot of space away from the first co, things feel fresh again.

There should be a rule on boards that you do not make any moves on CEO for 2 weeks after a PR crisis (excluding criminal acts). Boards are often compelled to make decisions under public pressure but once that subsides there's a great clarity about what to do.
Nobody should be surprised by this. This is why I started Particle—there must be an answer to taxing humanity on intelligence. We will drive the cost per task to zero.
Is this real? Is Anthropic really trying to compete with every company in existence?

I think the folly of Anthropic is believing you can control AI at all.
The capitalist in me gets it but this won’t go unanswered by society. Anthropic will continue to gatekeep until your products can’t use their models or you can’t make certain things that they’ll compete with you on.

@bernhardsson Jevons doesn't typically involve price alone. But an efficiency that's introduced which drops price and creates the rebound. So, another way to compare is the integral of margin (aggregate margin dollars) before and after.

I have never been busier over the past 4 years since GPT-4. There’s still seemingly zero risk of this for engineers, at least. This past month, I recently have found projects that take the normal 2-3 weeks again. Of course, these projects would’ve taken months. There’s a wide frontier out there.
I get the worry about AI taking all the jobs but it sure seems like engineers are harder to get and more expensive than ever 🤔
