I'm glad I'm not the only one. I couldn't make it past the first paragraph. He says he doesn't care for safety and type systems, and then says what he cares about is making it work and making it fast, both of which are significantly aided by safety and type systems.
All he's saying is he doesn't care about the features, just what they let him do with them. Type safety in and of itself isn't interesting to the author but he appreciates it's benefits.
If that's the case, the author would be well-served by rewriting the first paragraph to make that clear. The way it's currently written does not communicate that to me at all.
