Improvements in single-core performance (the kind that matters for Javascript and most real-world applications) has been near-stagnant for many years now. Your projection also implies that programmers of the future won't also produce exponentially slower code. I have doubts about that, considering how unresponsive programs these days are, compared to their counterparts of two decades ago (when most programmers actually cared about performance).
