Somehow I missed this last night.
Wonderful post.
It's like grabbing a thread and pulling it, following the logical progression of ideas.
Doesn't matter so much to me if the tech can do exactly what we envision as the worst case scenario, but more so what the underlying goal is.
The guest-friendly parts of NextGen are purely the by-product. No guest ever asked for NextGen. Guests want newer/ better attractions and better maintenance.
Disney wants more money from guests (understandable for a business) and rather than plus the parks to get it, they want to use mined data to get it. That's my main complaint. Nothing about NextGen appeals to me. Nothing. I want the newer/better/improved attractions, not a pre-booked Fastpass. No thanks.
As for the privacy concerns, we'll have to wait and see how it plays out. Too much is unknown for most people to really take a hardcore stand on either side right now.
I will say this, though...there are enough worrisome aspects to warrant taking a very close and skeptical look at the whole program.
Anyone working too hard to defend it at this point...well, there's an old quote about "The lady doth protest too much." And it doesn't have to be a lady.
