You have to be able to design language to start doing it. We do not expect random people giving other people drug recipes to become doctors just from their experience of giving drugs.

I'm horrified by onset of events when it does not fail, not when it does. History of programming languages knows a lot of exceptionally bad programming languages that got finished due to persistence of their authors, and got wide approval and usage.
