background information: I own and personally drive both ends of the spectrum, a 2014 model car and a 1970 model year truck. The 2014 has all the available electronics features. The 1970... the only electronic device in that vehicle is the ignition module; and, that was an upgrade (I hate setting points). The 1970 truck doesn't even have power brakes. I'm not a luddite. Hell, I make a living as an engineer working for a company that designs and manufactures sensors; I'm not going to argue against technology.
To the point: I read this discussion and I listen to people talking about the active cruise control and collision avoidance systems in their cars and I come to an unfortunate conclusion... These systems can and do lead to people becoming less attentive while they drive. I totally get that these systems save lives. It's just that I see people becoming dependent on these systems and not using them as they are intended.
Would you like fries with that?
Would you like butter on your popcorn?
I bet they'll get a charge out of that.

So many options... so little time... I have to go to work now.
By some estimates, Gliese 710’s passing will cause as many as 2.4 million comets to move into Earth-crossing orbits. As noted in my book “Distant Wanderers,” these comets will only gradually arrive in our vicinity over a period of some two million years.
So, not an immediate threat; but, a threat non-the-less.
Generally I'm agreeing with you.
I think the reason you're not hearing them talk about recovering 2nd stages is their program of incremental improvements. Once they have a system for recovering the 1st stage working, and have successfully launched a couple of F9Heavy boosters, I think you'll see the 2nd stage recovery talks come back.
NASA didn't trust the "re-usability" of the Dragon enough to allow this (at the time) untested vehicle to be re-attached to the ISS. Assuming they get the contract for crew launch, that might change.
