A few themes stand out this week. Physical AI is arriving as a distinct scene. AgentCon kicks off Monday in Mountain View, the 133rd SF Hardware Meetup goes robotics and Physical AI on Thursday, and the Physical AI Hack World Tour runs all day Saturday. The weekend is becoming a real programming layer. Six events land on Saturday and three more on Sunday, with hackathons like Physical AI Hack, MeDo Vibe Coding, Open Source Computer Use, and Build Smth AI-Native all landing on the weekend. The architecture debate is also moving into the practitioner community. Lukasz Kaiser, co-author of “Attention Is All You Need,” is headlining a Transformers versus Post-Transformers event at a community meetup, which signals that model architecture is now showing up in practitioner conversations. So as you look through the week, don’t just pick the obvious room. Find the event that fits your lane, or the one just outside it. Before we get into the full lineup, there’s one event from this week’s theme section I want to call out. The event is “Transformers vs. Post-Transformers: The Deciding Round, with Lukasz Kaiser,” presented by Pathway and hosted by Claire Nouet and Zuzanna Stamirowska. This one stands out because the post lists Lukasz Kaiser as co-author of “Attention Is All You Need,” and the session centers on a technical question that many AI builders are now paying attention to: transformers, post-transformers, and what comes next. It is happening Tuesday, May 5, from 5 PM to 8 PM PDT in San Francisco. This is an in-person event. Look it up on Luma if model architecture, AI systems, or the next phase of AI infrastructure is part of your work.
