Before Roger Bannister ran a 4:00 minute mile it was believed to be an impossibility. After that milestone, many people ran four-minute miles. YouTube is like that. I see children playing riffs on guitar that were originally only possible if you were a rock star or virtuoso. And yet, they are playing it perfectly because (I believe) they saw it done on YouTube or an instructor posted a video showing them how. Back in the day if you needed something fixed in your home you called a specialist—because you had no idea how to do it. Now, most anyone can watch a video and do minor repairs themselves. This is not a bad thing, but it shows us how our belief about what we can and can't do can hold us back. Seeing it done helps us see what is possible, and how to do it.
Each generation learned things in a different way. Baby Boomers read about something to figure it out. Generation X learned by doing. Millennials Googled it. Generation Z watches videos. What will the next generation do? Probably use virtual reality and artificial intelligence. Each generation seems to leap frog the other in expediency, efficiency, and exceeding expectations.
