The 4 most-needed embedded AI skills right now (mined from job posts + forums)
Not a guess. I wrote a small tool that crawls Raspberry Pi / NVIDIA official forums (for 'asked but unanswered' questions) and HN hiring threads (hiring = money), then crossed them to find the 4 most-needed embedded AI skills: multi-sensor time sync, edge inference optimization, on-device agents, and firmware/OTA + AI deployment. Evidence and hard parts included.
