Why are elderly people so confused with technology most of the time?

My grandma has had an iPhone for years and still doesn't know how to use it… She always asks me to help her with things that are so simple. Same with my granddad and my older aunts and uncles. They seem like they don't know how to use the simplest user friendly technology and when me or someone else who is young fixes it so easily they think were magicians. I know they didn't grow up with technology but really, is it that hard to figure out? (Not trying to offend anyone btw)

Screen messing up on iPhone 6?

So the entire thing went into pixely colors and then white when I opened up safari and then I closed it out and now all the corners/sides of the screen are changing brightness. I hard reset it and still nothing, the brightness is still going. I tried to screen record to send it to my family but now I can't stop recording.
