I'd say Tesla is the leader or could quickly become the leader given their intense investment in FSD. If a car software can "understand the physical world" using vision Ai / neural nets, it shouldn't be out of the question to reoptimize that software for the rest of the "physical world". Especially when you need a whole lot less safety standards compared to a 3,000lb 70MPH vehicle. Hell, the Optimus engineers said they were considering doing the first demo on a road since the software was so similar lol.

With FSD 12.3.3 released, it's clear FSD is getting smarter and smarter. How many of those releases left until people trust Optimus to fold their laundry? 1.0 Optimius will still be pretty dumb, but could still be worth the price (especially with continuous software upgrades!)
