a venn diagram of good leader qualities and charismatic qualities has non-trivial overlap. A leader lacking people skills has a very limited ceiling in what he/she can affect.
And perhaps delve into 'charismatic' as it relates to loud, aggressive or overbearing.
Just because the physical connection is gone, it does not mean a robotic / formulaic approach is now the only way to lead/manage humans
Nobody is suggesting 'robotic' or 'formulaic'.
Charisma does one thing: Make other people work for you and let you steal their output and take credit for their successes.
The leaders of the successful Asian tech nations don't seem that charismatic, but rather competent and intelligent. The West should take note.
And in two companies I worked at, the minute a charismatic, clueless bureaucrat swaggered in, took over the orgs and started barking orders (in a polite and charismatic fuck-you way), all top developers left, as if by magic.
