Amex Global Business Travel: The World’s First AI Take Private with Long Lake CEO Alexander Taubman

No Priors · 2026-05-11

Speaker 1 | 00:05 - 00:28
Today, know priors were joined by Alex Topman, the cofounder and CEO of Long Lake Management. Long Lake recently announced their intent to acquire American Express Global Business Travel for $6,300,000,000 in what I believe is the world’s first AI take private. They have previously bought around 30 companies, and they transform and optimize them with AI. So we’re very excited to have them on board today. Alex, thanks so much for running Acid Enterprise.

Pleasure to be here.

Thank you for having me, Elon. You just a…

  • This works really well btw, at the end of your query ask your LLM to “structure your response as HTML”, then view the generated file in your browser. I’ve also had some success asking the LLM to present its output as slideshows, etc.

More generally, imo audio is the human-preferred input to AIs but vision (images/animations/video) is the preferred output from them. Around a ~third of our brains are a massively parallel processor dedicated to vision, it is the 10-lane superhighway of information into brain. As AI improves, I think we’ll see a progression that takes advantage:

  1. raw text (hard/effortful to read)
  2. markdown (bold, italic, headings, tables, a bit easier on the eyes) <– current default
  3. HTML (still procedural with underlying code, but a lot more flexibility on the graphics, layout, even interactivity) <– early but forming new good default
    …4,5,6,…
    n) interactive neural videos/simulations

Imo the extrapolation (though the technology doesn’t exist just yet) ends in some kind of interactive videos generated directly by a diffusion neural net. Many open questions as to how exact/procedural “Software 1.0” artifacts (e.g. interactive simulations) may be woven together with neural artifacts (diffusion grids), but generally something in the direction of the recently viral

There are also improvements necessary and pending at the input. Audio nor text nor video alone are not enough, e.g. I feel a need to point/gesture to things on the screen, similar to all the things you would do with a person physically next to you and your computer screen.

TLDR The input/output mind meld between humans and AIs is ongoing and there is a lot of work to do and significant progress to be made, way before jumping all the way into neuralink-esque BCIs and all that. For what’s worth exploring at the current stage, hot tip try ask for HTML. [13038 ❤️ 1338 🔄]

  • I believe the kids call this “@thinkymachines just brutally framemogged gdm and oai”.

basically everyone’s definition of “realtime” just got a massive frciking upgrade [798 ❤️ 31 🔄]

  • You can now listen to me and Joe read out Claude’s constitution as an audiobook. Working on adding the option of listening to it on fast mode :) [416 ❤️ 22 🔄]

  • run claude agents for a control plane in your terminal!

after, hit &lt;- from any cli session to register that with the control plane

personally, i like to run claude agents from my root code dir to manage all my claude code agents in one place [327 ❤️ 25 🔄]
