Can Tesla's technology be ever duplicated by the competition?

I should add “as long as Elon is the CEO”. However, since the guy is about 50 and in good health, I expect him to be CEO through my remaining years and well beyond.

What brought this question to mind is a Youtube video featuring Sandy Munro – see below.

For those of you who do not know who Sandy is, he tears down cars for clients, and provides feedback to his clients. I am not certain that Elon or Tesla is a client, or if Sandy tears down Teslas just for fun.

Here is the link:

In this video, Sandy talks about Tesla’s Battery Day, in which Elon talked about the improvements Tesla is making in their batteries. And a few other things.

After watching the video, I became convinced that not only is Tesla way ahead of the competition, but likely to remain far ahead.

What do you think?
