In the distant future, I suppose a specially designed AI will analyze the information passing through our brain during solving tactics and provide a feedback on what we are doing wrong and what we should improve on. 
Taking tactics to a new level
Sort:
Just wonder how TT will look in the future. I'm not talking about the algorithm, but visualization.
I'm thinking graphics and animation. not necessarily 3D, but more like the use of glow effects and shading pieces by their importance maybe?
Highlighting pins, skewers, etc. making the position look more simplified
Maybe even animating every branch of a given position in some order.
It just seems to me, that it will train our brains to analyze the board easier.
now I just wonder when... a year from now? 5, 10?
