I think the "language of the future" will be the one that will allow people get results fast with little or no training. In other words, something that requires low skill. People hate learning and all they want is a magic button that just makes things happen (for the record, writing this doesn't make me happy at all).

Also, I predict something similar to the industrial revolution in software engineering, when high-skill difficult manual labor is replaced by factories operated by cheap low-skill workers.
