Back during the last Internet bubble (think drive-by venture capital and sock-puppets), I was part of a team that was developing high-reliability systems for the telecommunications industry. My manager at the time called me into his office for a chat about what he was looking for in his team.
“Gray,” he said, “We are going to change the Telecom world and the only way we can do that is with a team that is absolutely expert in Telecom and only Telecom. I don’t want any generalists. I want people who are an inch wide and a mile deep.”
