Even though that is Chinese propaganda, it is something we should be developing and inventing right here in the US but I guess we've been "distracted" and basically paralyzed for the past few years (decade+). China continues to steal US tech and improve on it and then they invent the rest to fill in the holes so that's where we are....I should go back and find that thread where someone mentioned the US is more than smart enough and capable enough to lead the world in technology. I think I may have replied "capable" is not a strategy.
