I don't know what's funnier, 7-22 on 3s, or 36-43 on free throws

Hi Roland,

Sailplane.ai, backed by AI kingmaker Khosla Ventures (OpenAI's first investor) and seed specialist True Ventures, is building a "self-driving cloud" - intelligent agents capable of autonomously managing the largest and most advanced AI infrastructure on the planet. Think "Waymo for cloud infrastructure".

I guess instead of β€œUber for X” the cool kids are building β€œWaymo for X” now?

I tried one of those car vs. bike calculators and with some pretty conservative assumptions it seems like the car comes out comfortably ahead on costs?

Study links adoption of electric vehicles with less air pollution and improved health Related News Study finds health disparities in PFAS levels linked to drinking water, food access and industrial pollution November 21, 2024

I do not think this is well supported by evidence. It would be better to have fewer cars overall, but every study I've seen suggests that even if we just replace ICE vehicles with EVs, there are substantial benefits to air quality, including PM2.5 pollution

I agree executive turnover should probably be much higher at most companies. But I still think having an *interim* CEO specifically is usually downstream of some earlier governance failure.

Is β€œone of the best … a tech company could ask for as an interim CEO” like β€œone of the best at complex residential mold remediation projects?”

Like, you probably want someone good, but even better not to find yourself in that position?

β€œWhile the board of directors and the company have nothing but praise for where Jack has taken us, we also agree that the best way forward is for Jack to step into the role Chairman, and for me to become CEO.

Reminded of how 2008 Twitter assured everyone that Jack would β€œbe closely consulted for all strategic decisions” for some reason

I think it can often be cheaper in money and energy than having a messy fight in public.

And anyway there's always energy for corporate politics, eg 2008 Twitter making Dorsey β€œChairman” when they pushed him out as CEO

Pats on the back all round as Pure Storage announces new CEO and growing revenues Scott Dietzen chairman now, Charles Giancarlo takes reins

It's not bad even if it was the board's decision! and I do think that's the most likely explanation

I was at Pure for this, and it worked out fine for everyone, even though it absolutely was not Scott's idea (and they had a replacement queued up in advance)

this is absolutely not true, boards shunt CEOs into do-nothing roles with fancy titles all the time (not saying that's necessarily what happened here)

More seriously, am I translating corporate speak correctly if I read β€œstepping down and being replaced by an investor on an interim basis” as β€œfired by the board on short notice”?

I appreciate everyone thinking of me, but I must emphasize that I am not currently in any discussions for any role at bluesky

The fastest Apple M5 Max is ~150 TOPS (trillions of AI acceleration math operations per second), a single Nvidia B200 is something like 20,000 TOPS (and 192 GB of RAM!), and they ship them 72 in a rack.

one underappreciated fact is that there are like 100 β€œneoclouds” out there right now that you can go to and run open weights models
