^^Preach about the downsides of the bike boom. Biggest issues I have seen is a general lack of road awareness and proper behavior.
As a biker, nothing drives me up the wall more than a fellow biker acting like a complete idiot or being inconsiderate. There is zero reason to run a red light or a 4 way stop. There is zero reason to be riding 3 abreast. When riding 2 abreast, keep it tight and compact because anything less than that defeats the purpose and doesn't make it any safer for cars to pass than a long single-file line. I can't tell you the number of times I want to pull over and lecture fellow cyclists about their poor behavior.
However, FWIW, I don't see the uproar about heavier bikes because 99.9% of the riders out there would be better off losing 1-2 pounds off their body than their bike. When it comes to disc brakes, I agree that there will always be rubbing, even if it's minor. That being said, I do think there's a segment of the users out there that do benefit from them. The biggest benefactors I see are those living in hilly areas and like using carbon wheels. I know the risk of delamination is pretty slim but it can happen. Disc brakes almost entirely remove that possibility. The second biggest benefactors are heavier riders. Like it or not, discs do stop a hell of a lot better. And for heavier individuals that can help.
And yes, road ain't gravel and gravel ain't road. But all-road can do both

.
I picked up a nice Ti gravel bike with a CX geo that's pretty similar to my roadie and I have to say it's a lot of fun. Nowhere near as snappy but it is so smooth. A slightly more relaxed geo is appreciated as well when I'm going for a more casual ride. Haven't had the chance to take it off road yet but hoping I'll find some decent gravel in Ithaca this fall.
I'll try to get some pictures of it up later this week. It's got a sweet racing blue color pattern with some Mavic carbon rims+rainbow anodized spokes.
