You can build a supercluster of massive computers, but if the coordinators are not able to map good tasks onto the appropriate resource or reduce the output into something coherent and comprehensible, your cluster is going to be sitting at 99.9999% idle time.
And just as you can't stick supercomputers exposed to the elements in the Mojave with a 3G connection and expect them to last more than a few more minutes without crashing, you can't stick good coders in an environment that's not conducive to their group and individual welfare and expect them to do anything except crash.
Humans have much less consistent performance output than machines, no matter how "10x" people think you are. They are even more sensitive to their environments than delicate computing devices. They require a lot of coordination and organization to output something useful.
Everyone ebbs and flows. Focusing on productivity multipliers usually ends in disaster. In most cases, today's raw skill is much less important than a realistic, productive worldview.
This extends beyond hiring. For example, selecting a spouse based on present qualities is much less intelligent than selecting a spouse based on their attitude and worldview and the changes that worldview is likely to precipitate, regardless of the current state.
