You're both right. It is much harder to clone Waymo. Doesn't mean that there isn't a second mover advantage. Plus the amount of patents involved in this mean even if you're burning money down a dead end you might stumble upon an insight / patent that would help regardless of the approach taken. Often time with engineering a good design comes out of a known shortcoming of some other subsystem.
