As technical people, we tend to have a bias that we're better equipped to understand things than anyone else, but that's often not the case. Many, many of the things out there don't just require the ability to use Google and do math, but also those things engineers are notoriously bad at like understanding human systems, compromising, and communication. We also don't have any particular advantages in knowing things outside our domain of expertise. An all-engineer government is definitely not an ideal.
