These things remind me vaguely of the 'Ludovico treatment' in
A Clockwork Orange. I don't think it's good for your eyes to remain staring at a fixed spot for extended periods; treating the fact that 90% of time reading is spent on saccades (eyeball movement) as a problem is like saying that time spent walking around your home or office is also wasted, and that we'd be better off using Segways.
Literacy deficits are a big problem, which won't be helped by displaying the words faster. So is shallow, uncritical reading. Like the chording keyboard, sequential word displays strike me as a solution in search of a problem.
