I disagree, although the games may be the same as mindless play. Kids just don't care how mechanical things work and most have the "Just Call Someone" mentality. When most of us were kids, we didn't have the "Gadgets" and to figure things out was a challenge. Now to jailbreak a phone is what they consider a challenge. As a father of two kids and I used to make my son work constantly with me in the garage. It would have ben my dream growing up for my Dad to have a garage full of atvs to play with and work on. He is much more interested in instagram, youtube and worthless fiddling. His fan light recently burned out and he told me about it, light still works in my room, you deal with it. Turns out it was the whole light assembly, not just the bulb, still I told him, you deal with it or sit in the dark, he did for awhile, then he went to Lowes and got a new fan light kit and fixed it. Most parents don't even force their kids that hard. A lot of his friends don't even know what "Vise Grips" are, unless they look it up on their phone.
Knowing what vise grips are is less relevant today than ever before. In fact, knowing how to operate an IDE or navigate a file system via shell commands are skills that will better serve young people today.
Also, I know of at least one study that shows video games as a positive for brain development. You may view them as wastes of time, but in reality most are highly elaborate puzzles. Heck, even the dumbest ones help you hone your reflexes and quick decision making skills.
