Threety printing is just softwar riven manufacturing and automation. If we could print an entire rocket, that would have a hundred ims fewer parts. I believe in what relativity's driving towards us well be able to build a rocket from raw material to complete in under 60 days. And then 60 days later we can do a better version. And 60 days later than that, we can doet an even better version. Bcause there's fewer constraints with treety printing, you can iterate much faster. It strikes me that there'ster some similarities here, at least on a high level, between kind of electric cars and the internal combustion engine.
