That doesn't make any sense. Use the right tool for the job. If "the winner" was all that mattered, we'd all be using Java now, and it would remain the top language forever, as long as it makes any sense at all to use -- not even requiring it to make more sense than other options.
Technological progress often evolves as a Scale Free Network[1] where the nodes with most present activities are likely to see the highest investment. It is less of a problem for mature ecosystem and tools, but being in the "not winner" position will likely induce negative effects in the long term technological progress. (I am sure there are many counterexamples) [1] https://en.wikipedia.org/wiki/Scale-free_network
Sufficient investment for significant ongoing value is a matter of a threshold relevant to the particular needs served by the target technology, not of rank. As long as there's "enough" interest, it will have as much likelihood of stable or increasing value for (appropriately targeted) users as anything else.
Meanwhile, too much investment from too-big interested parties can ruin something pretty thoroughly.
Things are not as straightforwardly popularity-contest-driven as you seem to suggest.
