I sense Oracle soil will collapse quite fast. JVM speed can only keep people interested so far .. and a lot of smart people are into language and compilation these days.
From my observation it’s much easier to recruit Java devs than Node devs, for example (I’m located in an average city, not a leading one like SF or NY). I’ve closed my Node projects because it seems to be too early to recruit and train interns in this area.
Being able to easily recruit programmers in a popular stack says nothing of their quality as professionals though.
If anything, I've seen a lot of non-programmers disguised as Java programmers. Armies of them in enterprise teams. A truckload of expense for not much gain.
I'm not saying it's everywhere like that of course. I've met brilliant Java developers when I contracted for SAP.
So how do you deal with such a risk?
If I had to hire I'd search programmers of less popular languages -- and only 3-5 of them. These people tend to be insanely productive and have very good perspective and culture.
