More people or things contributing to a goal does not always add more security/efficiency/capability to achieve said goal.

A classic example is a length of chain.

The more individual links, the more weight the chain as a whole needs to be able to carry.

Each link needs to be able to support the weight of the load and the weight of the entire length of the chain.

More links also introduces more opportunities for links with failure points to be included.

Neither visionary nor a founder.

I have absolutly seen people who are unskilled at picking up and moving boxes. It’s not a task with a high skill floor, or a particularily high skill ceiling, but it exists.

And somehow my company has been uniformly capable of identifying and hiring these people.
