How about a campaign to share the best advice @RonConway gave. Ron was my first angel investor I was considering selling my 1st company to msft He drew a chart on whiteboard. He said β€œyou have to crawl back up that hill if you raise $ The problem is the x-axis is time”

FSD 14.3 truly has killer visuals. @elonmusk and Tesla have been cooking.

LFG! Congrats Kurt!
Access granted. You have found your way to the Marathon. The ice around Cryo Archive cracks and groans. It seems nothing can stop you from getting in. It will be interesting to see if you can get out. 10 AM PT, March 20, 2026

As we're getting closer and closer to seeing the doors open for the Cryo Deck of the Marathon Ship, please be advised when it does open: surviving will be a challenge for even the most prepared of crews. (Everyone will have something new to learn). But we believe for those of you who are brave enough, it'll be a journey that you'll remember. TL;DR: Cryo Deck is a Pinnacle Challenge in more ways than one.

Probably something every startup should watch... Demos can sometimes go wrong :)
A Sekiguchi Genetics experience.

Played Marathon for 9 hours last night. Has exponentially more depth than other extraction shooters I've been playing. From player classes, to faction missions/ skill trees/ stores, weapon customizations/ enhancements, runner enhancements, much stronger AI enemies. Not to mention ranked. It feels like a strong mixture of several titles that creates a different experience when put together. Extremely solid game with a very bright future, especially with speed of updates we have seen from the team. The negativity seems completely misplaced imo. It feels like people didn't make it into skill tree unlocks or higher tier armor and gear before they went onto socials to join a hate train πŸ˜…

My little agent/slackbot started as a bot that just auto-wrote investor updates for me. Now it also writes stories about fleets. It also crawls all of our meeting notes each day and coverts action-items into linear tickets if they fit our OKRs.

Prediction: @Tesla ends up with huge amount of power steering pump failures because FSD doesn't consider wear and tear on the pump or the tires Fix by moving forward first then gently turn the wheel.... @elonmusk

Its crazy how openai has gone from helpful partner to the intern from hell Constantly asking questions and clarifications I get they need to reduce load on their servers but sheesh! Here is a made up example "Print this out" "Would you like that on 8 1/2 x 11 or Legal?"
