Machine gunning with a camera at mega frames per second is not photography in the purist sense. It is using a camera to do a job which I have no need to use. When I was using a camera for a task in hand usually involved a tripod. There was no need to fire of dozens of frames to get one possible good one. Static objects. landscapes. and even portraits tend not to move very quickly so I have no real need to learn the technique.
It is the difference between constructing a flat pack piece of furniture using a screwdriver, compared to making it from scratch with skills, knowledge, hand tools and experience gathered over the years. I know what I prefer.
You have said you have no experience of photography where you can benefit from high FPS or AF.
I have experience of 5x4 and medium format tripod mounted landscape photography with film (but now using digital) as well as wildlife (and a little sports photography) with film and digital; my views differ from yours
With sports photography and wildlife photography, you don't use high frame rates hoping to get "one possible good one".
You still use the same skills of timing and composition to "capture the moment" that you did before having high frame rates available. But, by anticipating the "moment," you can start a "short" burst of pictures to capture a few pictures before and a few pictures after the moment. You may well be running at 20fps but you might end up with only 5-10 (on rare occasion more than this) pictures to choose from.
With sports and wildlife, lots of what is happening is outside your control. For example with flying birds, you will be not only trying to watch every aspect of the birds behaviour, ie wing position, head position, beak open or closed etc, you also need to monitor the background as you pan across it following the flying birds, even if you have chosen you position to give a good background. On many days the light may be variable and changing rapidly so you also need to time pressing the shutter when the lighting is at its best Added to this is the extra complication of more than one bird flying, so you are also trying to capture several birds at the moment they make a pleasing composition.
I could probably add to this list, but with sports and wildlife, the moment you need to press the shutter is changing rapidly, as multiple, outside of your control, factors are changing, all of which will affect the success of your photograph.
You also need to keep the bird of primary interest in focus. Even with autofocus, there are myriad AF options, each with specific applications that you need to learn and apply. Even during the actual shooting, you need to be conscious of what is happening, and possibly override what the AF is doing (or not doing).
With so much going on when taking wildlife and sports photographs (not with every picture, but with a high proportion), being able to use AF, allows you to concentrate on the less mechanical aspects of sports and wildlife photography (ie composition. lighting, gestures and timing). Using short bursts rather than a single shot reduces the risk of a shot being ruined by all the things outside your control. Hopefully, if you have timed your burst of shots properly, at least one of them will come together the way you had seen it in your head when pressing the shutter, and you will have avoided something you didn't see ruining all your shots from the burst.
Overall, I would argue that even with high fps and AF, the knowledge and skills required for consistently "good" wildlife photography (and sports photography, but I cannot confidently comment on sports photography) is no less, and arguably higher than those required for consistently "good" landscape photography.
I have used "consistently" carefully because one consequence of digital, with AF, and high FPS is the increased chance of a "lucky" shot, but I am assuming a comparison between the working practises of enthusiast and professional sports and wildlife photographers and the working practises of enthusiast and professional landscape and portrait photographers.
Finally, regardless of how much you prepare and your level of skill, with nearly all photography there is an element of luck.
