Even the best performers need structure and guidance - a coach. Without coaching, high performers can meet all sorts of suboptimal fates…

Why don’t tech companies generally employ coaches? Yes you can get an “executive” coach, but not widely and really depends on the culture for the perceived purpose. Coaches aren’t widely available for helping people using (and not abusing) their brain’s gifts every day.

Probably some kind of worry "but what if we spend our money coaching them... and then they leave?"

The same reason tech companies generally don't spend money training their employees, etc.
