Soul is hard to define, almost impossible to nail down, and too damned easy to argue about (as we have demonstrated). A camera, like a musical instrument, can help facilitate the creation of a work that some or many of us might agree has "soul", but it can't embody it. So a Leica M7 is more or less on the same plane in this regard as, say, an M9. (I don't claim that big-ass dSLRs, for example, necessarily deny soul; I just think they suck for a lot of other reasons, starting with their sheer size. 😉)
Yes, there's the issue of TV and the Web; there are also all those camera-phones and Flips and games and apps and all this motion that keeps us glues to all kinds of screens, big and small, which scatters our attention and reduces our perceived time to pay rapt attention to one thing... a sonata, a painting, a sense of time flowing past without our hurtling through it with grim determination.
(Okay, I should lay off the Rilke late at night, but you might get my point.)
Soul takes a little time, even if the image you just took, so full of same, took a fraction of a second. It's the thought behind the picture, conscious or otherwise, deep or fleeting, that really makes the difference. Soul doesn't require Big Thoughts, at least not all the time. But thought does count. So does feeling. And the two need not be diametrically opposed.
I much prefer the boxes I put film into. Leave me stranded with something digital*, however, and I'd cope.
