Jay Robinson has a two-pronged tale:
This reminds me of an old saying: If you’re the smartest person in the room, then you’re in the wrong room.*
Now, this is not a commentary on my current team. I work with some really smart people, and I’m very grateful for that. But while my teammate may be one of the best PHP or Node.js coders I know, that doesn’t necessarily translate to an expertise with the .NET Framework. The true test is this – no matter how smart they are, if they’re not catching my mistakes, then I’m not being held accountable.
There is some good advice here on threading (yes, definitely use the newer threading libraries), but also good advice on surrounding yourself with intelligent people who can catch your mistakes.
