> consortium of companies invested in using the runtime
I believe this is very unlikely to happen. If the founder (Ryan) was involved in it or it have strong market position, it would have strong chances.
Now, is a kingdom without a king and without strong companies to steward it forward. I hope to be wrong though!
Maybe in another decade he'll pop up again with a third runtime called something like "Edno" that tries to do things differently than both Node and Deno. There are plenty of permutations of those letters left!
