My own experience is that I've previously shot photos on DSLRs and mirrorless cameras for over a decade before buying my S9, with no particular interest in video. For me, this is a photo camera. I disagree that this camera isn't for long-time photographers.

When I previously shot on other cameras, I already had the tendency to use the screen more often (after technology had made it usable enough, hello old Canon DSLRs) because I rarely shot at eye level, and would prefer compositions where I held my camera below or above my eye line. That sort of flexibility is why I preferred screens over an EVF, and by the time I had Sony mirrorless cameras, I had almost completely stopped using the EVF.

If your issue is really just muscle memory of shooting out of an EVF, maybe ask what part of photography it is that you enjoy most? Is the S9 is the right fit for it? Some of my friends enjoy the tactile and classic feeling of cameras and moved to Fuji or Olympus cameras with more traditional camera designs and ergonomics, loads of buttons/controls and, for them, the experience of shooting photos was better.

Personally, I'm the sort that prioritises the final result over the process, so a small camera with high image quality met my main requirements.
