Even if they never get anything else to work, it will have all have been worth it for self parallel parking.

I enjoy driving, so I don't want an AI to take the wheel, but the first time I had a car tell me "Yep, I can fit in there" and then park itself in the spot, was the most joyous tech-experience of my entire life.

I was in a good mood for the next few days.

Even if all progress stops, they have made the world a slightly better place.
