科技大咖John Carmack(@ID_AA_Carmack)谈了自己对机器人的看法，对人形机器人（ humanoid robot）的近期实用性提出了质疑：
I am more skeptical than a lot of people in the tech space about the near term utility of humanoid robots.
Long term, driven be AGI, sure, they are going to be an enormous economic engine, but business plans that have them making a dent in the next five years seem unlikely.
Tesla can play a long game and maybe win, but I don’t like the odds for startups.
Always happy to see tech exceed my expectations, of course!

我比科技领域的许多人更怀疑人形机器人的近期实用性。从长远来看，在 AGI（通用人工智能） 的推动下，它们无疑将成为巨大的经济引擎，但让它们在未来五年内产生影响的商业计划似乎不太可能。
特斯拉可以打持久战并可能获胜，但我看好初创企业获胜的概率不大。
当然，我总是很高兴看到技术超出我的预期！
Elon Musk接话，披露了一些关于机器人Optimus（擎天柱）的情况：
Well, Optimus is already doing some tasks in the factory and the scope of its ability is increasing rapidly.
The toughest part by far is improving the design of Optimus for ease of manufacturing and tooling up a complex supply chain, so it can be made in significant numbers.

好吧，擎天柱已经在工厂里执行一些任务了，其能力范围正在迅速增大。迄今为止最困难的部分是改进 Optimus 的设计，使其更易于制造，并建立复杂的供应链，从而实现大批量生产。
在Elon Musk看来，人形机器人Optimus的能力不会有问题，一定会快速增强。他更关心的是Optimus的规模化制造和量产，以及后面的成本。这是他一贯的作法和风格。
