After one attempt at photography in high school, with a SLR and a darkroom, I decided to wait until I felt that the tech had matured enough so that I never, ever had to deal with physical film media. Reciprocity is a perfect example; when I'm in art mode (or scientific data collection), I never want to think about the nonlinearity of my sensor.

Digital sensors get noise instead of reciprocity failure. That’s why the original Acros was so loved for long exposures
Film has noise too. It's called "grain". It even mirrors how DSLRs work pretty directly: Higher ISO values result in more noise/grain.

Not quite. Film doesn't get more grain with longer exposures, whereas it does with digital sensors, as you can get [hot pixels](https://photofocus.com/software/what-are-hot-pixels-and-how-...) and other artifacts the longer the sensor is exposing a shot.
