I'm mostly referring to the younger generation(s) and the apps most widely used by them. Think of the simplicity of applications like Instagram and Snapchat. There isn't much to the interfaces for most user interaction - some images, videos, text, an input or two, and a few buttons. There may be some advanced touch interactions (pinching and swiping), but overall, applications these days tend to be relatively simple.

Older generations definitely struggle using software though, so I think they may be a good metric for how simple and easy to use software can be.

Anecdotal experiences could certainly play a role in my opinion here, but I do think I've recognized a pattern over the past couple of decades where winning software interfaces have made a transition from being overly designed and complex to much simpler designs with (usually) predictable interactive element positions and flows.

Think of what software was like when there were "shiny" buttons and small text everywhere with confusing visual flow, and then think about what it is now, usually composed of flat buttons (e.g., the "material-ui" standard) and easy to digest visual flow with predictable interactions. This transition is likely a natural result of figuring out over time what works best and what doesn't.

By tech savvy people, I mean the end users who interact with software on a regular basis. These people (i.e., most people in the modern world, a number steadily increasing) will naturally gravitate towards the easy-to-use, predictable design patterns to which they've become accustomed.
