"That lack of programmability is probably what ultimately will doom vi. It can't extend its domain"

This quote by Bill Joy recommends that the absence of programmability in the full-screen editor vi will be its downfall. Vi is a full-screen editor that is utilized to produce and modify text files, however it does not have the ability to be programmed. This implies that it can not be encompassed do more than what it was originally designed for. As innovation advances, the requirement for more advanced and programmable full-screen editor increases. Without the ability to be set, vi will not have the ability to stay up to date with the competitors and will eventually become obsolete. This absence of programmability is what will eventually result in its failure.
