Which is really pity, but you can't expect too much. Watching the presentation, I felt that Elon wants to make an impression of XXI-century spacecraft - but he doesn't want to get into shoes of Doug Engelbart making a thing so great nobody will pay him to fully use that. No, Elon firmly wants not the perfect, but profitable solution. Which is very understandable. There are multiple places where SpaceX could really try to do better. The problem is, they'd spend much more money and time and get much less predictable results. Considering they already pushing envelope pretty hard, it's likely a wise decision to also use some more proven technologies.
