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 😅.

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.

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. 🥴
