Technology

There's a subgroup of the millennial and gen X that grew up with a sweet spot of computers such that you actually need to know how it works in order to use one effectively. Ease enough to do a lot of fun stuff, hard enough that it encourages learning the technical minutiae. The rise of smart phones and net/chrome books means there is a huge chunk of population that has a superficial and passing relationship with tech. It's big buttons or else it doesn't register with them. It's not their fault, the pursue of usability and fool proofing without actually giving tools to dig deep when necessary means they have less exposure to the underlying tech. Thus are less familiar with how things work. It's an universal phenomenon, I would bet most people have no clue how to raise, grow and process food, but still we don't starve, we go to the grocery and buy what's there already cleaned, processed and packaged. There are huge advantages to understanding the chain of production of food, but I'd guess most people would struggle in an agronomy class about what's a compost bin.
