Absolutely wrong.
When it comes to what BTC is and using BTC, it is easy to understand.
Now if you are talking about understanding the mechanics of how it works, yes, that does take some technical knowledge. That applies to just about everything in life so, your point is?...
I agree, to transact a d use Bitcoin on a daily or regular basis in terms of sending, receiving,
buying, selling and HODL'ing its dead simple, just like everything there is a "getting to
know" period and after that its second nature.
Does everyone need to know how to program, test for bugs, develop new applications
and such? absolutely not, that side of Bitcoin is for the majority of us is indeed very
difficult to understand.
