Yeah, Photoshop has actions too. See, photographers have been doing computational photography too, this whole time. It’s just that we prefer to put it together with a general purpose tool, rather than what formula Apple or Samsung has decided would be best.

I understand carrying and taking shot with a DSLR is much more involved than pulling out a phone from a pocket, but have you ever used compact cameras with 1" censor like a Sony RX100 or Canon G9x ?

They both fit in your pocket and startup as fast as you can activate the camera on your phone. Out of habit I usually reach the power button inconsciently when grabbing it from my pocket and the lense is usually extending while my arm is moving in position so it is usually immediately ready to snap a picture.

If you are in a setting where you are almost certain to take picture, a micro four third format also works great and depending on the lense are usually small enough if you are the kind of guy who wears small shoulder or sling bags.

That somewhat depends on three main things: your photography style, your equipment quality, and your skill. If you shoot landscape photos, you almost certainly don't want to be taking 100s of shots per day and should spend more time and effort on composition. If you shoot wildlife action (e.g. birds in flight, especially fast ones like swallows) you'll be taking hundreds to thousands of shots per minute of action (30 shots/second from a high-end body like a Sony a1 or Cannon R5 means 1800 shots per minute, even mid-range bodies take 10 shots/second). If you've got good enough equipment and skill that most of those shots are usable, then there's going to be a lot of sorting to find the ones worth editing.

I find the best photo before editing is often different than the best photo after editing. Granted that’s probably a skill issue on my part.
