I don't know offhand what TSLA's stock price is, but I think it's fair to say that the speculative value is at least very high if you believe that Tesla Optimus is at all a viable competitor to Boston Dynamics Atlas. I see much more long-term potential value in that than the car business.

Robotaxi is also a pretty interesting bet. I'm skeptical that it'll pan out, or at least that it will ever reach the same level of safety as Waymo without lidar, but on the other hand AI has obviously significantly advanced and been significantly democratized compared to when Tesla first launched Autopilot over a decade ago. More significantly, I see the decentralized rollout strategy as a potentially viable path to beat Waymo to the punch of a full-scale deployment. Waymo might still get there first based on its headstart and massive warchest, but Tesla's strategy is essentially crowdfunding it while using the market to optimize geographic distribution. The downside is that allowing the Robotaxi to be used in arbitrary/novel locations might be significantly less safe and/or more computationally expensive than Waymo's approach, so it's a more uncertain bet than Waymo.
