Sketchpad is great, but I think that for an initial OLPC application, one
has to focus on the future integration and subsequent transition from human
instructor-based learning to computer-based learning.

I would think that the most simple mathematics will always be taught by a
human teacher because that human teacher to the child is a logical extension
(if not the same) to their human parent.  At that age (1-6) the human cannot
be replaced by a computer full-time --- however, the human can be
supplemented and enhanced through an OLPC software tool.

Sketchpad would be a perfect tool to facilitate/accelerate the transition
from human to a machine-based learning paradigm (ages 6-12), thus freeing up
the human resource to concentrate on the nurturing phase.  In developing
countries, educated human resources are very often a very scarce commodity.
Isn't this a fundamental justification for OLPC?
