#rationalwiki is now back and functioning without any significant outages for 3 days. 503 errors were apparently caused by an actor on #Alibaba Cloud doing scraping for #AI, and also affected other sites that were unprotected and unable to handle the #DDoS load.

Two important messages here:

1. It's not social media or cell phones.

2. Stop selling doom. We must insist to young people that the future is not written in stone and that they have the power to decide what kind of future they want to live in.

Essential reading for understanding the influence that The Extropians' outlandish ideas have had on many Big Tech CEOs' obsession with AGI.

With current pledges, the world's on track for 2.6°C of warming in 2100 compared to preindustrial levels.

10 years ago, before the Paris agreement, it was 3.6°C.

20+ years ago, we thought it would be 4-5°C.

1.5°C was a good target, but did anyone seriously think it was possible?

So 2.6°C is […]
