In short
Scott Shapiro’s tweeting is not:
•Primarily academic
•Neutral or detached
•Focused on promoting his own papers
It is:
•Politically sharp
•Institutionally focused (law, media, power)
•Witty, caustic, and intentionally un‑professorial

Ivana Bocevska comes tomorrow morning and talks about games and modularity at OOPSLA. I am trying to convince Ivana to dive into the unforgiving world of Positiv Stellensatz algorithms in z3. Please pretend to Ivana that i am not totally nuts..

Got on the mcp craze a few weeks ago. Added a minimal 20 line z3mcp server to z3 repo. It provides some nice entertainment in the vscode copliot environment or other mcp hosts to force some trust to answers.
