That is a strong opinion for someone who doesn't have any experience with them. Your opinions are based on assumptions not your experience.
Really, I have seen thousands of trail cam pics, none of them mine, but I have literally seen thousands of trail cam pics. Do I like seeing them? Of course. Do they have a place in my hunting world, other than to catch trespassers? Nope. To me they take away from HUNTING, they take away from the experience. I literally see pics most everyday, I generally do not pay attention to them, I have almost become immune to them. To me what fun is there in having a camera do the work, meaning I know of so many who will not hunt unless they have pics of a particular buck or just a good buck or just pics of deer at all. They literally don't hunt unless the camera is "telling them to". Not for me, I don't need, don't want and don't care about using cameras to look for deer. I like using what I see with my own eyes, whether it is when I scout (which I rarely if ever do) or when I am hunting.
I do have one experience with cameras. I have posted and said many times that after the first week or so in December, just seeing deer (a buck, especially a better buck is as scarce as bigfoot where I hunt, and not just for me but all the guys that hunt the land around us to) becomes extremely difficult in Tennessee, and I have hunted several counties. And that is even though there is sign everywhere. There have been seasons I have killed a pile of mature does, most of the time on a farm I was asked to come and kill deer, but December, especially after the first week, has always been tough for me.
The year, a few years ago, my daughter decided she wanted to hunt and really wanted to kill a buck, but, she wasn't able to go in November and did not start going til December. I explained to her how difficult just seeing deer was after November, much less a buck. We went every chance we got for just over a week, we never saw one deer, not one. That she got discouraged is an understatement, she was convinced there were no deer where we hunting at all. I keep a couple cameras for trespassers, I have been hunting the farm we were hunting (it is gone now) for over 30 years. I borrowed a couple more and put out 4 cameras, like I said I know this farm pretty well and we have never put a camera out for deer there. My brother and myself got together, sprayed down with scent blocker, gloves, etc. and put them out, thickets, trails that were mud (actually there are trails there right now, I still have about 20 acres to hunt, that are mud, look like deer highways). We never got one picture of a deer, not one, bobcats, raccoons, foxes, dogs, coyotes, etc. but zero deer and this farm for sure had deer, lots of them, thanks for the help from the cameras, NOT! I managed to convince her that cameras are basically useless and just because the deer don't show up on camera, that does not mean there are not deer using the place, being persistent is the key and not giving up. She stayed with it and missed a nice buck, partly my fault because I got to excited and partly because she had a small window to make a shot. A couple days later she killed a really nice buck. At least she learned not to depend on cameras. We kept those cameras out for that season and even tried a couple different locations and never got one picture of a deer, even though we had a rare ending to the season and passed some bucks and killed several does off of that farm.
Very limited experience, but I know all I need to know about cameras. Like I said, I don't even really scout, almost never, I for sure don't need a camera and I for sure don't have to see pics to hunt or to get excited about hunting.
