Been missing my Oura ring post shifting to Apple Watch for tracking both fitness + sleep. Started using Autosleep (iOS app, one time $5.99 purchase) last week, and I’m surprisingly impressed. I’m really into gamification via sleep scores, readiness, trend analysis, etc, and this does it all!

I don’t fancy myself a political commentator, but if you’re intellectually honest you must acknowledge that Democrats have been the more fiscally responsible party for 30+ years.

Optical computing encodes data in light beams instead of electric currents. Fully Homomorphic Encryption via optical computing would reduce processing time from 1 million seconds to between 10 and 100 seconds. Added bonus: no energy consumption/CO2 emissions

It’s surprising to me how in a span of months, I went through the following stages of belief: - I want to buy a Tesla - I don’t trust Tesla Full Self-Driving - I don’t trust Autopilot anywhere - I don’t trust riding in a Tesla - I don’t trust Teslas anywhere All this from one man buying Twitter.

Moved to NJ from India at the age of 16. Got a degree in Math, then was a Fortran programmer in the early 80s. Left the corporate world to raise 3 kids, moved to California, and now she teaches Algebra + Geometry at a high school.

Twitter used to routinely challenge Turkey’s takedown requests Erdogan actually had Twitter banned in Turkey in 2014 for refusing to comply. (the courts later ended the ban.) but that was on the “censorship” version of Twitter, not this new “free speech” one

The “AI safety” community seems to be split between people who have (potentially) addressable concerns about biased content, and people who saw Terminator too many times. Is this really the limit of our vision on this topic?

Getting a few domain-specific ‘breaking news’ accounts over here would be great for mass adoption. A close friend is a sports producer (ex-ESPN) and uses Twitter exclusively for sports-related news and discourse—apparently there’s no close alternative by a mile. And these communities are huge.

social media has revealed on a massive scale the section of our population that doesn’t have any critical thinking skills, so now all discourse becomes about how that section is going to interpret any piece of media (even when the intended audience is, as you point out, us)

My trip to the White House this week involved a lot of discussion about this. Especially the DEFCON bit. I’m excited to see crowd sourcing of AI security. While there are clear challenges, openness is definitely the way. Its also a GREAT opportunity for policymakers to engage and learn.
