I suppose the difference is that in most technical topics the complexity is either inherent (quantum mechanics just is this way) or exists for a good reason (consensus algorithms are complicated but they solve a hard problem).
IMHO this is not true in cryptocurrency, which is more akin to a self-sustaining pyramid scheme where the complexity serves to obscure the reality of the thing and draw in more rubes. All the nonsensical jargon around NFTs was trying to hide the fact that paying money for a URL to a jpeg of a monkey is stupid. As best I can gather, all this new "layer 2" nonsense is to try and hide the fact that blockchain is a slow, crappy database.
