And this is even before AI companies are expected to turn a profit. Definitely earlier than I expected, and not a good sign if you're investing in AI imho.

Donald Trump’s idiotic war has damaged the global economy and left British families and businesses suffering. A total disaster backed by Kemi Badenoch and Nigel Farage.

Working through the Easter holidays feels a bit like skipping a night of sleep, though arguably it could also be the food poisoning that makes me feel like that 😅.

Have you tried LinkedIn instead? Tends to have a stronger bubble effect and emphasis on praise in my experience. I'm okay with people getting upset at BlueSky. I moved here from X because in general their views are a bit more palatable.

Putin is helping Iran. Zelenskyy is helping us. Trump does not seem to understand or is ignoring these basic facts. Hope someone on his team will help the president correct this policy position and... Thank Zelenskyy. Arm Ukraine. Sanction Putin.

Why is Trump negotiating when Europe pays for everything and he’s a terrible negotiator acting in bad faith?

Hi all. Before our rapid rollercoaster descent into the economic abyss (?) let me remind you that not all computer science tools are AI, and many of them don't cost much to be useful. So please don't give up hope. Now buckle up and enjoy the ride. 🥴

What could go wrong has already gone wrong. The UK has 150 universities, many of them excellent in applied research. Only a set of donkeys would outsource their research whilst having those facilities in their back yard. But that is exactly what has happened here.

The Netherlands is trying to draw a line under a year of chaos with fresh elections – will it work?

Citing the worrying poll, but not the papers debunking it. Perhaps a wrong choice?

Dear community, last time you helped us reach lots of new BlueSky followers. Now that we see that there is an exodus on X, it is important that these people can also find us on BlueSky for all necessary updates about Ukraine. Would you like to share this message, preferably with a quote? Thanks!

I agree. I actually do not think they should be allowed to work full time, so you can draw my conclusion from that in regards to voting 😅.

If they can do so full time and legally, then they deserve a vote too.

16 year olds can work, so they should be allowed to vote. Sounds simple enough to me. I really don't understand why the majority would disagree with this.

In Nederland is het vrij makkelijk om van school te wisselen. Hoog/laagbegaafde kinderen in een thuisleeromgeving met 1 ander persoon plaatsen gaat ze echt niet helpen op de lange termijn.

Als alle slimme kinderen thuisonderwijs gaan volgen, wie blijft er dan nog in de klas? Thuisonderwijs is een slippery slope... uiteindelijk wordt iedereen sociaal geïsoleerd en kun je samenhorige politiek wel vergeten.

I'm sorry, but Israel lost my support over the last year. The targeting in Gaza has been atrocious. Iran is still worse, but the whole scene is not a pretty sight.

Derek Groen @whydoitweet.bsky.social · 17/06/2025
I'm not sure the West is really in the driving seat here. It seems to be mainly Putin who is intent on starting wars, ramping up arms production, and handing weapons to the likes of Iran and N Korea. I guess Israël is now having a go at that same strategy.
