I actually don't think so, not that I have downvoted you. V8 was such a breakthrough at the time, it blew off the competition. Since then, many competitors have picked up the tricks and as shown in the bennchmark, uWSGI holds its own against Node/V8. As a result, the Node/V8 combination is not going to be so dominant in a few years in terms of performance. Another factors will come into play such as the language and the libraries available (the ecosystem). I would find it much harder to predict the dominance of the Noode/V8 ecosystem compared to that of Python or Java in a few years' time.

I think this is it exactly. The pace at which infrastructure, support and tools in "competing" ecosystems can be improved will outpace the rate at which people's miss can be changed about JS. There are 10-15 years of the language's, most of which were a Very Bad time for it's reputation, and only recently has the community of developers begun to land on solid development principles -- and you can hardly call those universal. I think most people fear callback spaghetti when they think of diving into someone else's JS code.
