I just made up the years .. for example sake
a better way is to think who is the first in our lineage to talk and trade bitcoin .. if it's you , your kids will be comfortable with digital signatures..

Sure, there's a time lag, but digital signatures predate bitcoin by 30 years.
I am the first in my generation to know about digital signature .. my parents used pen and paper 100 percent and my grannys used thumb impression.. I guess , I am better represent of a normie :-) ..
I am pretty sure my kids shall use digital signatures as effortlessly..
I'd be agreeing if we were talking about mass usage, but I'm talking about large institutions using it, not everyday people.
A good analogy might be QR codes; the average user hasn't the faintest clue how it works, but it's easy for companies to implement.
