My guess is this will prove to be a historic milestone – from the perspective of future historians studying how humans evolved to be a multi-planetary species. I’ll stick my neck out to speculate that in 10 years major component reuse will be the norm.
I love good engineering! Yes I know that landing the first stage 1 out of 3 tries isn’t good enough. But isn’t it remarkable that SpaceX succeeded in only three attempts? How many more launches before they are achieving 80% success? That’s most of the cost-savings right there. Sure 100% will be nice someday.
Think what it would cost to fly to the South Pacific if Air New Zealand threw the Dreamliner away at the end of each flight:-)
