#2How long until radar becomes an afterthought, and we get an issue because a transponder has failed?

#3If there's anyone in the air control technology industry here, I'm curious what parts of this change get you really excited, and which parts get you really nervous?

#4Why would you change to GPS - when it is so easy to spoof/jam?

#5The same GPS the US Government reserves the right to reduce the precision when they feel like it? Seems risky idea to assume they will never do this.

Probably a very long time, there are national security reasons to keep American airspace under constant radar coverage and radars get cheaper and better as time goes on.

#7I very recently had my ADSB fail while flying in a piper arrow. I think its probably good to have redundant systems in place, its a core to aviation to do that with instruments. Also, the military jams GPS rather frequently for exercises: https://www.thedrive.com/the-war-zone/17987/usaf-is-jamming-...

#8To an extent, this sounds terrifying. The first thing that jumped to my mind is that GPS be jammed or spoofed. In fact, the U.S. military in its shift away from COIN to great power competition in possibly highly contested environments is training to have less reliance on GPS: https://www.zerohedge.com/news/2018-01-26/usaf-begins-massiv...
Radar can be jammed too, but I would guess the EM signature powerful enough to track. I don't know if GPS jammers would have that issue.
On a positive note, I think this would pave the way towards integrating commercial drone infrastructure into our airways a lot better!

The cost. This affects general aviation as older planes will require avionics upgrades. Otherwise I’m excited for the sheer amount of data that will be made available to the public. Now you will be able to track all FAA registered planes

I would hope aircraft would have multiband receivers that also support GLONASS, Galileo, and BeiDou. There's also Japan's QZSS and the regional Indian IRNSS.
