This is literally my experience with Gemini 2.5 Pro every other task I give it. Same with ChatGPT 5.0. So I'm not sold at all on the idea that these thinks are intelligent let alone intelligent enough to substitute engineers.

United Utilities website screenshot with a funny mistype of my first and last name

United Utilities "nailed" my name, it's like a cat was writing instead of a person. Funny thing is I cannot correct it through their website, so I have to call another representative hoping they won't type random letters this time.

French researcher, going to a conference in Houston, was forbidden entry to US; his work and personal electronics were both confiscated.

Why? Because a “random search” of his cell phone revealed a negative personal opinion on Trump and the Trump administration. www.lemonde.fr/internationa...

I'd love to use Bluesky more often, but its sign in system is completely broken. I have to reset my password every single time, otherwise it says the password is wrong.... For months now

Does anyone know any interesting Blue sky feeds? Currently my feeds are either a bunch of pets, or posts from companies.

London is much more enjoyable as visitor than as a resident. I also moved north (close to Manchester) and I don't regret it a bit.
