I have to agree with "teekay" on this.
I firmly believe that we all have the innate capacity to learn, and it is always to our advantage to do so. I can think of a dozen reasons for not learning what the mode buttons do and another dozen reasons for learning how to do everything in manual.
To my way of thinking, it is in the same league as teaching a man to fish instead of just giving him one of your fish. After you give a man a fish, by tomorrow you are both back where you started.
Once you learn how to use the manual controls (there aren't many - just shutter speed and aperture - we let you slide on focusing), you never have to worry about being caught in a situation you cannot deal with.
Regardless of what the aperture and shutter priority modes think they are accomplishing, and regardless of how "fully automatic" Auto is, I can always think it out just as well as those modes can without straining my brain too much.
I think of it this way, in general - you either have enough light to use your controls freely or you're hurting for light. If you're hurting for light and have no chance of using a tripod, then you set up for 1/30 if you are really steady (otherwise 1/60) and then you start with wide open lens and start stopping down until it says you've got enough light and fire!
If you're already out of gas with 1/30 and wide open lens, just shoot anyway and pray for post processing.
When you aren't hurting for light, just decide whether it needs to be stopped or not. If it does then set a shutter speed just fast enough to stop it. Then go twiddle the lens, as above.
The last condition is that you've got plenty of light and there's no problem with freezing motion - in that case you take your lens to its sweet spot and adjust the shutter speed until the lightmeter says it's enough and fire!
The only thing I left out was that rare case where you are afraid of not having enough depth of field, so you stop down as far as you can go instead of using the sweet spot and then twiddle the shutter speed to give you the light you need.
That's not many things to learn, is it? I'll be surprised if it takes more than an hour to get those down pat, which includes being sure you really understand each one - not just memorize them.
