Julian treats ‘prototype’ like a weekend hobby project, his idea of casual tweeting is casually teasing a robot that can fetch snacks while you argue with Yann on ML theory. He’s the kind of guy who sleeps with a torque wrench under his pillow and calls it R&D.

Shipped the first production-scale vision DNN at Google that automated Street View tasks, and now is leading Tesla’s Optimus AI toward production-ready humanoids, turning a research pipeline into real-world robotics demonstrations and a prototype production line.

To push humanoid robotics from lab demos into reliable, scalable products that help people, by rapidly iterating on autonomy, manipulation, and production engineering until robots can safely and usefully work alongside humans.

Believes in engineering-first progress: build fast, test in the real world, and iterate from failures; values scalability and manufacturability as much as algorithmic novelty; trusts that practical deployment is the fastest path to meaningful AI and robotics impact.

Combines deep research experience with production and manufacturing savvy; excellent at communicating concrete progress (high-engagement demo tweets); credible voice in both academia and industry; able to translate complex technical milestones into compelling short updates.

Can come off as overly confident or polarizing when debating peers; intense focus on engineering milestones may under-communicate broader safety/ethics context; occasional shorthand or inside-baseball posts can lose non-expert audiences.

On X: post short threaded breakdowns of each demo (problem → approach → failure modes → next steps), more behind-the-scenes clips from the production line, regular AMAs or Spaces to tackle critics live, and bite-sized explainers that translate technical metrics into everyday impact. Pin a highlight thread, use subtitles on demo videos, and engage top researchers and journalists in replies to amplify reach.

Fun fact: Julian helped launch the first production vision-based deep neural network at Google that automated Street View number detection, and today leads Optimus AI development at Tesla with prototype hands that can catch balls and robots that can dock, climb stairs, and hand out snacks. He has ~34k followers, follows 302 accounts, and has tweeted 387 times, so he’s prolific but selective.

I disagree with @ylecun on this. We have a pretty good idea at Tesla on how we can make general humanoids a reality very quickly. Funny anecdote: Yann was advising me to launch what became the first production vision based deep neural network at Google. His feedback: use convs, made a big difference. That neural network was classifying whether a patch of Street View image contained a street number in 2013. This + the one that read the street number that landed in 2014 automated hundreds of years of human labor. Fun times then and fun times now. Learned a lot from Yann back then, great mentor.
