Getting shit done and pleasing clients can be seen as "greatness." I write a shitload of PHP/jquery - and no one reviews my code. If it's done fast and works as expected my bosses don't care... and they'll listen to me over the front-end dev who wants to use React/Ruby. Now I don't 'hate' any language and will try new things, but my point is that the definition of greatness can be completely different between companies, especially when the company isn't a tech company.
