Most of what I had was based on Star Wars Episode I ... so get ready for your heart attack, grandpa, this has been going on for some time. 
No, I know what you mean. Rather than instruction-driven sets like what I had, I think kids learning to play with their imagination is better. I'm a little biased because my cousin, who has a double Master's in MIT and works on secret government crap, played with them as a kid, and I've always heard his interest in engineering was somehow tied to it.
Me, I was reading reviews for movies in the papers at three, so I was always quite advanced when it came to English ... would have liked someone to tell me print media and not talking like a fifth grader would die with the internet. At least I'm decently tech-savvy.
I liked K'Nex a lot as a kid though. I was ... different.
