Blade steel is a legitimately important consideration for fixed blades - there are certain things one might do with a fixed blade (chopping, etc) where factors like impact resistance make a significant difference. One could make a solid argument for needing a 4V chopper over 1095.
For folders, though, I find pretty much anything other than mystery stainless / 440A or the lesser alphabet soup steels (4cr, 3cr, 7cr, etc. 8cr and 9cr are alright) to be pretty much fine for any of my cutting needs. As long as it fits the price range, I'm cool with anything from 440C to Maxamet. They all have their properties that make them a little better-suited to this or that, and it's far more useful and important to just become good at maintaining an edge.
There are some distinct advantages to the particle metallurgy steels, but I feel like most of those advantages are largely lost on us since I would wager about 75% of what you do in a day with a knife could be accomplished with a key (or your bare hands. I don't use knife to break down cardboard - just tear along the creases, or fold larger sheets to make your own creases), and the rest probably with a moderately sharp SAK blade. I will almost certainly never use my Manix 4V in a manner that allows me to appreciate its toughness, but I want it and I like that it's made of such a ridiculous steel.
TL,DR: It's all fine. There's nothing wrong with liking super steels, but there's also nothing wrong with liking "lesser" steels. They all still get ground into blades that cut things, and it's down to your own preferences regarding sharpening and relative desire to feel slightly more pride of ownership because it has some exotic specialty alloy for a blade.
