Why are old people so against bitcoin and crypto assets?

I have noticed that whenever I bring up bitcoin older people (50 and up) will instantly dismiss it. One of my parent's friends told me "don't be sorry when it gets close to zero" and I just shook my head and couldn't help but face palm in front of him. He's an older person whose had "45 years of financial experience" and says that bitcoin is a "new fad."

I can't even give him a rebuttal because he doesn't listen and thinks he's right all the time. Its my responsibility to patiently "absorb his experience." All of my parents' friends think that bitcoin is some new age hype. But look at the world around us, everything is changing. We now have bitcoin vending machines in shopping malls and people are concerned about the rapid inflation in USD. Almost all of the central bank authorities at the IMF are old people who can't wrap their head around "blockchain technology."
