Silly idea I had. Wild speculation and generalisations. Here goes:

Does T Matter at All?

We never really know our Ts. Instead we interact with a projection, an idealisation. This is the whole point of the blank slate, after all. And the mirror and the brick wall operate on the same principle. The real T is a mere doll to dress as we like: it has no desires or beliefs that would give it a genuine personality. T isn't really there.

That being the case, why do we need a T at all? Couldn't we just stay home and imagine our Ts? Surely any reality that T lets slip just gets in the way.

At the very least, good Ts would be entirely interchangeable. (Is this an ideal that Ts set themselves?)
