Ted,
I get what you're saying and agree with most of it. But just because you own a DAW doesn't mean that you have to beat detective the drums. One doesn't have to AutoTune every vocal. Not every tune needs fader rides and compression. But Pro Tools might just make a great two track recorder, too. Half of the skill of mixing is in knowing when to make all the lights come on and when to leave them off. in the same way that space in music can be as powerful as full and lush. No argument there from me.
But when I walk into a room, I think it's important that I know how to operate the equipment in the same way you expect an airline pilot to have a good understanding of how to fly the plane. I know how to operate Pro Tools, and Digital Performer and Logic well enough that I don't even have to pollute my mind with the details of how the system works. That way I can focus on the music and not the mouse or the screen. That's why people call me. They know that when I leave, they will have something that they can turn in to the lable, or the network, or the Director that will sound good. I've been doing this for 20 years, so I also know how to use microphones, a tape recorder, and a mixing console.
I don't get your reasoning when you wonder how long the DAW will last. Things that are more powerful, cost effective, and work reliably don't usually fall by the wayside in the name of progress. They tend to improve and progress in response to the needs and desires of those who use them. Hopefully, there will always be horses, but I don't really want to ride one into Hollywood to work.
By the way, I hope you don't take me for an Extreme type of a guy. I named my studio Extreme Mixing, because when I started it by buying Pro Tools 5 years ago, it seemed like a pretty extreme--like extreme skiing, or mororcycle racing--way to work. I didn't really know if it could be done when I started down this road. Turns out it was just another way to accomplish the same thing I had already been doing for over a decade.
