I can't get behind tubeless tires, personally. I also don't want to use an electronic shifter; in my car, both of these are fine, on my bicycle no thanks.
These are not hard lines in the sand but I don't see myself crossing them anytime in the future. I'm not a luddite, but I grew up in the Boy Scouts and no one can tell me that with tubeless tires I simply won't get flats. The only way that happens is if I don't ride. To build upon that, no one will ever convince me that a flat won't happen at the least convenient time and place. I really want the ability to easily repair a flat and get on with my ride.
The same goes for electronic shifting. I don't feel like carrying batteries and I'm not good at changing batteries or charging anything besides my phone, my computer, and my hearing aids. At least once a year I find myself out on my bike with my Cateye Padrone (the most advanced bike computer I think I'll ever get) and either the head unit battery dies or the sensor battery dies. They are easy changes, but it always seems to happen out on the road and I always overlook the periodicity of that maintenance since there's no battery gauge on the device. So there's no way I'm going to allow myself to get caught out in BFE (or north Philly for that matter) without the ability to shift and fix my own flats.
