The language will fix a chunk of it. Much buggy code simply cannot be compiled, and if you can't compile it you can't ship it. You are mostly left with logic and design errors, which can become more obvious due to the language. Middle management will hate it because due to the language they lose much of their ability to compromise on quality, passing the buck. Upper management may love it or hate it, depending on how serious they are about improving quality, as the language forces the spending for that level of quality.
