Hassabis's first career was writing AI for commercial computer games.

Judge the proposition: Hassabis's first professional career was writing AI for commercial computer games. True: biographical records show his first paid professional work (e.g. at Bullfrog Productions on Theme Park, then Lionhead and Elixir Studios) was game development that included writing AI for commercial games, before his later academic neuroscience and AI-research careers. Mostly true: his first career was commercial game development and he did AI programming in it, though his main role was broader (e.g. lead programmer, designer, studio founder). Mixed: game development was an early career, but other substantial paid professional work came first or alongside it. Mostly false: he worked in games early, but not in an AI-writing role, or games was not his first career. False: records show his first career was something other than commercial game development.

4. E4 Demis Hassabis - Wikipedia Wikipedia · 28 November 2005 Own record

   “In his early career, he was a video game AI programmer and designer, and an expert board games player.”

E2 and E3 report that after university Hassabis went into the video game industry, at Bullfrog Productions and Lionhead Studios. E1 and E2 say he was Lead AI Programmer on Black & White, so his early work in commercial games did include writing AI. E4 describes his early career as a video game AI programmer and designer who was also an expert board games player, which suggests his role was broader than AI programming alone. In the surrounding text Hassabis describes game AI as his first career, and the evidence places his move into the games industry directly after university [E2][E3], with no evidence of an earlier paid professional career, so the proposition is mostly true.
