does anyone else feel that modern knives are too hard
No, on a bet with a friend maybe a year or two ago, I bought a double-sided sharpening stone for sale for $1 at a dollar store and used it to reprofile my Benchmade 940 in S30v to paper-cutting sharp. Given that S30v is perhaps the quintessential super steel and a $1 stone could sharpen it, I can't agree with this statement.
Lundin argues that modern steels nearly require a hi-tech sharpening device of some kind
Similar to the above, absolutely any knife steel can be sharpened with a stone, and a single stone at that. People use sharpening devices because they don't know how to freehand or want better precision than they can freehand, but neither of those implies that steels today require such devices.
have grinds that are too hard to sharpen --
IMO (and I know this will meet some, perhaps strong, disagreement) the scandi grind is a horrible idea all around. The supposed purpose is to make sharpening in the field easy. Let's break that down into two parts, making sharpening easier and sharpening in the field.
It is the grind that requires taking the most metal off the knife to get it sharp. That makes it the longest to sharpen, and that contradicts that it is the easiest to sharpen.
Of course its philosophy leans on the idea that it is a mindless process to sharpen it, and that is what makes it "easiest". If you know how to sharpen a knife, you can sharpen it in the field, so the only people this is helping is the people who don't know how to sharpen properly. The real solution is to learn to sharpen your knives before taking them out into the field. ... and it is not hard to learn. I, and the rest of my cub scout troop, knew how before we learned to drive. All it takes is a cheap knife for practice and a measure of patience.
I would argue Lundin chooses softer steels because scandi grinds require taking more metal off, so super steels do not lend themselves well to the grind. Honestly, everything you cite by Lundin appears to me solely informed by him not knowing how to sharpen his knives well. All of his concerns and complaints are resolved by learning to sharpen a knife properly.
and blade shapes with limited utility in many cases
I will have to strongly disagree with this. The 'tactical' phase that knives have been going through in the last three decades or so has swayed them to make them do-everything tools. People want a knife that will cut their bagel in the morning, pry open a crate at work, and pound in that loose floorboard they notice walking in at night. In comparison, look at the traditional knives from a century ago; they each had a specific job in mind and were named for it. It is telling that you still find spey blades on knives today that aren't marketed to farmers. It is also telling that today one-blade knives make up the vast majority of tactical folder designs, while multi-blade knives, each with its own purpose, were more popular in the past. Before the more general-use designs of today people did fine, so IMO it's hyperbole to say today's blades are too limited in utility.
