I don't agree that the SpaceX landing is better than Apollo 11. I don't measure something in "How available is the technology to me?". I measure in "How hard is that?". I'm not downplaying what SpaceX did to be controversial.

I'm just of the opinion that the challenges that NASA had to overcome 50 years ago to get to the moon involved alot more "unknown" information.

I think anyone who has wanted to do "something that's never been done before" can appreciate the trailblazers that had no other option than to make an educated guess because algorithms, processing power, failure modes did not exist.
