Imagine being Warren Buffet's age and having his level of success.
Then imagine that some disruptive technology comes along and threatens the empire you built. Are you likely to spend your last decade jumping in and figuring out this new thing while being trolled the entire time or is it just time to sip your Coca-Cola and do the trolling yourself?
I'd like to think I'd jump right in but at his age and station in life, it's hard to know.
