I think that's just down to the fact that she's always having to relearn the interface anyhow. I have tech illiterate family members who always manage to do whatever they intended with the device, just in the most insane ways because to them there are no conventions and habits, only whatever they figured out.
I agree with you, but at the same time I find myself having to relearn interfaces all the frigging time anyway.
I get it, I can't expect to get into "the zone" without investment into detailed and up-to-date knowledge of my current environment, and any relearning is at best merely incremental and at worst a brand new trend that is (or will become) widespread enough to be unavoidable.
But I can't stop envying the superficially "naive" stoicism of those waning generations who only wanted some kind of glorified typewriter and anything else they've got along the way is still gravy on the top.
