> One of the potential benefits of FSD is that it will save lives

But that doesn’t mean that tesla will save lives. Maybe they do a bunch of this and learn that cameras alone aren’t sufficient, and then waymo wins. Tesla wouldn’t have saved any lives, only killed a couple people unnecessarily.

Medicine is the classic example of applying this kind of thinking. You could do all sorts of unethical medical testing to speed up medical research, saving countless lives down the line, but we don’t because it doesn’t make it right.

With another medical example, you could roll out snake oil without testing it thoroughly because it’ll save lives if it works. But maybe snake oil doesn’t work, and it’ll be some other thing that works, and by rushing the snake oil, you just made things worse.
