Who cares what Zack Arias has to say. His main talent is self-promotion, i.e. he's not much of a photographer. His major source of income seems to come from being a guru/media whore/pitchman. If he wants to maintain that income he has to stop acting like a hopped-up loon.
His understanding of photo history leaves much to be desired. Back in the day many magazine covers were shot with 35mm cameras (gotta love Kodachrome). Photojournalists stopped using 4x5 and 6x6 during the Vietnam War era.
Now-a-days no-one except pixel peepers care about sensor size. No. One. Cares. Got that -- No. One. Cares.
Professionals are shooting paying work with everything from iPhones to 8x10. The impossible Project is now making New 8x10 Polaroid film https://shop.the-impossible-project.com/shop/film/8x10inch/fi_8x10_1_imp_2_mum
So please don't bore me with senseless sensor wars. No. One (except you). Cares.
Why should we care what careless people think? (except when their carelessness affects our quality of life)
Why careless people need others to support their careless beliefs? (except when they do it for money)
Why bother fighting for carelessness? It makes no sense. (except when you're a troll or doing it for money)
