As long as we use current interfaces, no one
would deny it. But after reading some stuff
about Epigram language, I wonder if those
ideas could not be used to write a better
interface to computers. Then, all those tasks
would be handled by your interface plug-ins,
not by programs.

Really, we need to do all of that today. But
I believe reading from keyboard, files
etc. should not be part of programs we write
daily, just a task for a basic interface to
which our programs should be linked.

Best,
