Can't tell if this comment is serious. No, there are individual people who are capable of writing operating systems, browsers, source control systems, complex video games, and programming languages with no external guidance, design reviews, or anything. They are fully autonomous intelligent beings with good taste, powerful programming ability, and the vision to set long term and short term goals, craft plans, and execute without outside supervision.

There are also small teams of experts who need little to no supervision, and will NOT devolve without constant correction. They will do things like look for an existing function before writing a new one, or use good judgement when trying to find a library, rather than reinventing the wheel.
