Can we agree that the name of FSD was selected before it actually was capable of anything? And if that's the case how should they have named it: "someday it might be full self driving"?

I totally understand your point, and I also agree with it, but I also can understand the point of view of someone as ambitious and driven as Musk that saw an idea, and then committed to it by choosing a name that reflects what they intend it to become, not what it's capable of doing at the moment.

You can see this very pattern if you watch Shawn Murray's first interviews about No Man's Sky. He shows the game as being capable of doing all these wonderful things that were proven to be bullshit when it was first released, yet over the years the game was built almost into the state that he first wanted it as. Was that an intentional way of cheating people, or was it just an ambitious person telling you about what they see at the end of road for their project? In my opinion it's the later, but people that bought into the hype at launch day, I bet they felt pretty angry.

So my advice (and apologies if it sounds patronizing), if anyone is in the market for buying a product which sounds too good to be true, maybe research the fine print and the owner's manual before putting your life and others' in danger by trusting the marketing team's selection of a name.
