I would like what you say to be true. However, I have three of the base skills you mention, but I can't get the time of day from most companies unless I did it

I would like what you say to be true. However, I have three of the base skills you mention, but I can't get the time of day from most companies unless I did it in their language or platform of choice. I think it is just a reality of the current state the industry is in. Everyone seems to want developers who are already trained and experienced in what they are using so they can "hit the ground running", at least for non-junior positions. I think that is the biggest impediment for more experienced developers.
