The young ones can’t concentrate. And their productivity is vastly lower than that of we oldsters. Their code quality is way lower. That’s why they care more about testing than development; short attention spans make for buggy code.
We read Donald Knuth and learned from him; the kids read Stack Overflow, and copy from it. We grew up reading books; they grew up channel surfing and playing games.
But I no longer like the industry. The methodologies are bullshit, the lingo is intolerably stupid (stories, technical debt, refactoring). I can’t stand being interrupted by meetings all the time.
You underestimate the value of experience.
