Her point was that in 10 years we will be using crypto and blockchain in ways not yet even imagined. When the internet was first created who could have imagined the impact it would have for commerce, communication, and information sharing.
I remember youtube was just a place where you could upload and share family videos. Look at what it has become today. I remember when I first heard of facebook and thought Twitter was dumb testing it for the first time, and thats just 0.0001% of the internet.
Oh I agree with that 1000%. We are going to have use cases in a decade that we cannot even imagine. The first iteration is to replace what is known. Hence we see new technology as a replacement for what is in front of us. It is the second and third generations that really set things in motion in a big way.
