Anyone reading this post has an IQ higher than the average person.
Really? Why?
To answer your question:
Adoption takes time. It is like watching paint dry. First fiat ATMs were installed in 1969.
How many 80+ yr olds are using them today? Chances are that your friend will never use bitcoin, his daughters might use them because
their kids will use them. If you are in your late 30s and not using bitcoin today, chances are you'll never trust the technology and will refuse to use
it even if it replaces all fiat cash.
For the full adoption, you need to have at least one new generation born with that technology. Look at what happened with the Internet.
If it wasn't for youngsters, Internet and social media would never take off the way it did. I remember explaining TCP sockets to people in 1990,
they were all looking at me like I was an alien or I have completely lost my mind. I get the same reception with bitcoin.
Young minds are more malleable. Once you finish your formal education (aka brain castration), most likely than not, you are brain dead.
You need an open mind to accept new technological breakthrough. Think "tabula rasa".
So if you want a broader adoption, talk to your kids, explain the technology to them. I find it is much harder to convince someone in their 30s (or older)
to use bitcoin than it is to convince a teenager. 10 minutes later, teenager will be using bitcoin. Older folks, well, not so much. You might get 1 convert out of 30.
