My kids do the same kind of stuff today. I agree that kids today are just as capable (if not more) than my generation. But that isn't what that kid did. The beginning where he "ran across stumps" and the end where he skipped monkey bars were by far the easiest sections of his routine. The middle part would be very difficult for most children to string together. I would wager that less than 1% of children his age would be capable of performing that sequence without error and in that timeframe - regardless of dedication and preparation.
