Investor Dean Williams once wrote:

“Expertise is great, but it has a bad side effect. It tends to create an inability to accept new ideas.” Those who learned how to invest in the ‘70s and ‘80s never quite shook the idea that low inflation could persist as long as it has. Those who invested through the late ‘90s will perpetually see a bubble in anything that trades over 20 times earnings. Anyone under age 25 will have an easier time seeing the potential of blockchain than those over age 55. Same was true for the internet 30 years ago.”
