How did he make the graphs?

I do wonder what will happen, when everybody starts making 80% solutions. When I use three 80% done third party libraries will I get (10.80.8*0.8 =) 51.2% done library?

Does 80 percent solutions only apply to the highest level?

You don't choose a language in such case as you don't build with Ruby nor with Python. You build with the language and a web framework such rails or django.

There are many things to consider. And most of the issues ar non-technical

- will there be support for the frameworks, language etc long enough?

- are the coders competent with the language / framework

- what limitations exists on deployment

- what limitations the customer imposes

Of course if there's are no non-technical issues to consider, go for the technically "best" solution.
