I remember a joke I read once said "If someone from the 1970's appeared today, what would be the hardest thing to explain to them"
The top response was, "I possess a device in my pocket, which can access the entirety of knowledge known to man, I use it to look at pictures of cats and argue with strangers"
And although funny, i think it marks a good point, although we've advanced so far, and what we're capable of today is so amazing, if we really focused on advancing we could achieve amazing things
