Today, @RachelReevesMP announced that Sovereign AI will officially launch with @alexgkendall at @wayve_ai on 16 April... Lets get Britmaxxing 🚀 🇬🇧

Big news from Tokyo 🇯🇵 @Uber and @NissanMotor and @wayve_ai have signed an agreement to deploy supervised robotaxis in Tokyo from late 2026, bringing the Nissan Leaf powered by the Wayve AI Driver to riders through Uber. This is what scalable autonomy looks like: • OEM-native integration - no retrofit. Nissan is designing the vehicle for mass production, with hardware sourced from global automotive supply chains. • AI-first autonomy - a single AI Driver designed to generalise anywhere across Tokyo without mapping. • Collaborative and scalable path to autonomy - together, we combine intelligence, engineering and distribution. Tokyo is an exciting city for us to deploy our embodied AI. It’s a city with sophisticated mobility options and high safety standards. I loved testing our autonomy here this week. We’ve been public road testing and working closely with local authorities since early 2025. Looking forward to working alongside great leadership of Ivan Espinosa, Sarfraz Maredia and @dkhos. Big efforts ahead. 🙌

A German startup has just signed an agreement to build the world’s FIRST nuclear fusion plant. @proximafusion has signed an MOU securing €400m from its home state of Bavaria to build the €2bn plant. The rest of the funding is expected to come from the federal government. Proxima Fusion is hoping to get the plant up and running by the early 2030s. It comes at a time when Europe’s energy security is being scrutinised more than ever. Germany in particular has been criticised for closing down all of its nuclear power plants, but this could see the country become a global energy powerhouse. Backed by Wilbe, Cherry Ventures and Balderton, Proxima has become one of Europe’s most exciting companies. If this works Proxima could truly become a trillion dollar company. It is AMAZING to see European founders building the most exciting, and potentially impactful, technologies in the world.
