With the advent of Facebook and smartphones in every pocket, people tend to waste all their time on that sh*t and thus have far less time to actually learn any hobby or skill like homebrewing. If they want to brew, they're happy to blow the cash on fancy crap so that they don't have to understand what they're doing but can get it done anyway. Or can buy gifts for friends with the same problems as they have. A lot of products these days I think are intended more as gifts from the wealthy to the wealthy as opposed to things you would actually purchase for your own practical use.
As for me, I'll never buy any of it as I am happy as a clam brewing on my stovetop, BIAB, with buckets and colanders and a hose, the same floating thermometer and hydrometer that I got back in 1999. No chiller, no aeration, no stirplate -- that's all unnecessary expensive crap. I do have a mill but that was a gift. The blender worked just fine for "milling" the grains before that.
I think there is actually a resurgence of "craft" everything - beer, cheese, kombucha, pickling, smoking meat, cold-brew coffee, - among millennial hipster types, which could be putting some steam into home-brew industry. I get a lot more questions about my home-brew from 20-something than from 50 or 60-somethings.
And people buying fancy expensive equipment are not the 20 year olds, they are usually seasoned brewers - probably baby boomers - with extra cash to burn. Many of them are more interested in recipe formulation, and want brewday to be efficient and hassle-free, and so they may not care about DYI projects of piecing together a brewing system on the cheap. Or they already have it and want something more beautiful and efficient.
I don't blame them and I can't guarantee I won't go that route at some point. I can certainly see the appeal of push-button, electrical and automatic system. (for now I am happy with my 70qt Coleman Cooler converted to mash tun, 50" home-made immersion chiller, 20G pot with home-made valves for 10G batches, a dozen or so fermentors, mostly PET kind, a dozen or so kegs and 9 tap keezer with 3 nitro taps I DIY - I could argue my current setup is more functional and flexible than BIAB on kitchen stove or extract brewing, plus bottling, but it also cost a lot more $$ -especially the keezer parts - same could be said about 1bbl conicals or automated push-button brewing).
This is actually the great thing about home brewing - you can produce good or even great beers with some knowledge and very basic setup that cost about $100 (extract, kitchen pots, 1G jugs from apple juice, thermometer you may already have, hydrometer and some basic sanitizing/bottling/transfer equipment), or scale up to BIAB, and all-grain, convert coolers to mash tuns, drill holes and install ball-valves in 10G or 20G pots, make your own immersion chillers from copper tubing, scale up to kegging by converting freezers into keezers, or you can keep going and get into stainless steel conicals, electrical, fully automated, HERMS/RIMS, glycol chillers, oak barrels for aging, nitro taps, water chemistry, you can re-harvest your yeast and grow your own hops, roast your own grains and make your own candi sugar/syrup, design and print your own labels, wax or cage your bottles, or you can buy kits online and keep it simple, and focus on some other aspects of brewing. In other words - go from $100 to maybe $10K and up.
I think it's great that everyone can find their own price point/comfort/convenience point, geek out on cool shiny equipment, or immerse themselves in DYI projects, one can geek out on biology (yeast, mash process), physics (heating/cooling, and carbonation/gas handling), or chemistry (water salts/acids/pH), or keep it super basic and unscientific and still get great beer in the end.
