Unactioned ChatGPT tabs are the new browser tabs. I give AI a research task and then take forever to get back to it to read, digest and take action based on what I’ve learned.

The ‘psyops’ revealed by X are entirely the fault of the perverse incentives created by social media monetization programs.

Tried ChatGPT group chat with some friends. What an annoying, needy, know-it-all member of a chat it turns out to be. I had a completely different expectation for a useful interaction model in my head. Let's hope they iterate.

I really wish more scientists & artists were on here. When I go to in-person gatherings it’s really clear what a small sliver of us are here.
And I get it, how many social media collapses do you have to weather before you just give up?
But organizing would be so much easier if we were all here 😭

Social media enveloping traditional media means everything and everyone is now competing in the entertainment market. Boring stuff like policy that affects millions of lives doesn’t stand a chance.

Excellent analysis of 'peace plan' (in reality, more likely a plan for a renewed war in a few years, at most). The point about the US acting as a mediator between NATO & Russia reflects something I've noticed about Trump before - he often speaks of NATO as though the US weren't a member. Not good!
Some notable things in what's being called the "Trump peace plan" but which could not have been more clearly written in Moscow if it came with a 2 for 1 deal on tickets to the Bolshoi Ballet. 🧵

Europe's electricity system is changing rapidly and often in places that don't make the headlines.
Look at Estonia - not that long ago and fossil fuels dominated around 90% of electricity generation.
Today solar and wind eat more and more into the share of fossil fuel-generated electricity.
