Not really. It is just bunch of gear heads with lack of talent, but gear as the hobby are dominating most of "photography" forums. Those ain't really photography, but gear heads forums.
You seems to overpaying attention what gear heads are up to. While majority has switched to mobile phones or Instax cameras and they taking and getting pictures more simple than ever. Majority of those who are taking pictures, not those who are dominating "photography" forums.
maybe, but i think there are people who aren't gearheads who still believe what the salesman/woman might tell them, that more expensive might be better quality
better ergonomics, easier to use without a "fight with the equipment" .. there are plenty of people whether they are in photography forums or hanging out with friends / family
who for whatever reason believe a bigger negative probably gives them a better photograph ... and an even bigger negative will give them an even better photograph ...
and new lenses are crap, and old lenses are the best. there are posts here on apug every few months or weeks about how wonderful leica lenses are, or how this 1854 french landscape lens
makes these negatives that are so 3 dimensional you think you are looking at a hologram. they aren't all gear heads.
sure larger cameras might give better negatives, and certain cameras might be easier to use and easier to use might mean less to think about and more photograph making.
maybe it is the idea that when we learn the basics we want better to prove to ourselves we are worth it, and have graduated to the next level? but the reality is there is no next level ... just more gear to be bought

and advice from friends, family, internet people ( real ones and 13 year old girls posing as a 60 year old retired pro ) and everyone else ... who love your work
maybe i am romanticising what it must have been like in like 1890
using film that seemed to have more contrast than midtones but still
people were able to make photographs with as much ease as someone putting tri x in a m3 and "souping it in d76 "...
and be extremely excited that the film and box camera worked, and you didn't need to pour your own wet plates,
or use a mamouth plate camera when you took the train to california from nyc and made photographs of the plains or mountains
and they looked as good as the pictures you saw in books.
i wonder if the very fact that it is so easy in 2017 to make a photograph ( by whatever means ) it it takes the thrill out of it
