Tesla is not doing all that well with self-driving cars. They're behind Waymo, Zoox, and Baidu in Level 4 systems. (Level 4: good enough for a taxi service). All the major manufacturers have a Level 2 system now. A few have a Level 3 system where the driver can sit back and watch, but has to be ready to take over, which is where Tesla is now.
There are at least 18 humanoid robots far enough along to have YouTube videos, none of which are commercially successful. There's no reason Tesla will dominate that industry, if and when it gets going.
When those industries get going, there's no reason to expect they will have high margins. Humanoid robots compete with low-wage workers. Self driving cars compete with Uber drivers.
