Grok 4 Wows, The Bitter Lesson, Third Party, AI Browsers, SCOTUS backs POTUS on RIFs
All-In Podcast
· · Hosts: Chamath Palihapitiya, Jason Calacanis, David Sacks, David Friedberg · Guests: Travis Kalanick, Keith Rabois
Summary
The conversation focused on whether Grok 4 marks a real shift in frontier AI. The host argued that xAI’s rapid progress, massive GPU buildout, and heavy use of synthetic data point to a “bitter lesson” future: general computation and scale beat hand-coded human knowledge in more and more domains. A guest pushed the idea further, saying the same dynamic could produce scientific breakthroughs if models become good at the scientific method and can test hypotheses quickly in the physical world.
The panel then applied that framework to products and markets. They discussed AI-native browsers from Perplexity and OpenAI as an early but potentially unstable category, with one guest calling browsers a weak capital allocation choice in 2025 and suggesting Perplexity should focus on replacing Bloomberg instead. They also weighed Elon Musk’s new third-party political ambitions, with one guest arguing that although Elon is unusually capable, a new party is unlikely to work because American politics is already highly polarized and effectively operates through party takeover rather than true third-party success.
Key takeaways
- The host said Grok 4 reflects the “bitter lesson” thesis: scale and general computation can outperform human-engineered AI approaches.
- A guest argued that models trained for science could unlock new breakthroughs if they can rapidly test hypotheses in the real world.
- Keith Rabois said Perplexity’s browser push is a “great hail mary,” but that the real opportunity is replacing Bloomberg, not building another browser.
- The panel agreed AI browsers point toward an agentic future where users ask for outcomes, not web pages.
- Keith Rabois said Elon Musk is more likely to be a replacement-level politician than a successful third-party builder, despite his record as an entrepreneur.
Notable quotes
“the bitter lesson is you could believe that, you know, food is this immutable thing that's made meticulously by hand by these individuals”
“what it essentially allows you to do is view any problem as an endless scalable search or learning task”
“the other crazy thing that he said subsequent versions of Grock are not going to be trained on any traditional data set that exists in the wild”
“I think building a browser is an absolutely stupid capital allocation decision. Just totally stupid and unjustifiable in 2025”
“The idea of Elon creating a third party is for any other human being like absolutely absurd and ridiculous”
How the episode opens
I have a very funny story to tell you. Jason, where have you been? I've been trying to text you.

if you have a chance to go to Lake Ko. Anyways, this is us at Pasal Aqua. Who's the beautiful woman there?
Is that the woman who owns it or something? Is that the queen? That's not But the best part is we had such a good time.
You know how they have like a registry book to leave a message? Sure. So, I left a message.
Here we go. What a truly magnificent place. Above and beyond any expectation we had.
Go below. Go below. That's not for me.
Thank you. We took everything. The free We took everything.
The free bird. Oh my god, Jason. The hangers.
Okay. The laundry bag toothpaste, the robes, the slippers, everything. Absolutely fantastic.
Listen, you're going to have to send a bill to the free birds. Absolutely. We'll let your winners ride.
And that's it. We open sourced it to the fans and they've just gone crazy with love. All right, listen.
We've got a great panel this week. It's the summer. Things are slow.
Some people are busy. I think uh our prince of panic attacks, our dear Sultan of science is uh he's at the beep sax is busy. Couldn't make it this week in his place.
another brilliant PayPal alumni and uh dare I say GOP supporter, Heath Ra Boy.
