I think this is fine and where us crypto enthusiasts go wrong - most folk neither know nor care how the internet works (myself included!) and the same is true with the blockchain. I wouldn't even mention blockchain.
Maybe explain as the "next version of the internet" or a "new internet that will get rid of middlemen". This might enthuse and/or fill some with terror for the future of their livelihoods (myself included, again!!! lol)
It's tough hey. I suppose in the end I just need to let go. They are all free to do whatever they want... and they are still welcome to borrow money when I am a zillionaire ;)
Haha, yes..."this time next year, Rodney...!!!"
