Achieving 100x results isn't something you can guarantee, and it doesn't even involve writing a lot of code. It comes from blocking off a week to automate a task, and never having to deal with it again. It comes from having the experience and political capital to veto a project that would have wasted a year, because you've seen it go wrong before. It comes from improving some tools for the customer service reps, so that they're 5% more efficient (which then adds up to hundreds of hours a day if you're large enough).
Anyone CAN do this, but the people who have the insight, motivation, and skill to actually DO it are rare, and a smart organization should desire to keep them around for years just in case they do it a second time.
