But you still don't instill that actual individual in minds, and an actual, non-abstract, particular individual is occasionally crucial to a thought. Without that word you would basically go back to that activity in which pairs of folks try to find out a thing without using words. This is a bit of an auto-proof as I can't say its word.
It's not as if you can simply work around and pick similar words for that individual's particular noun, you miss almost all of a thought by dancing around it vs. using a fast shortcut that quickly aligns thoughts with low odds of ambiguity.
You could point to Mr. Musk by using his South African origins, but also with circumlocutions such as:
Zip2 collaborator
X.com collaborator (by and by, part of PayPal, of which a principal and also a primary joint stock-holding guy, and so an original PayPal Mafia "mafioso")
Mars colony instigator, for which aim's promotion also principal of orbital propulsion firm with first major victory involving launching an orbital craft propulsion unit again and again
Popular luxury voltaic-propulsion motorcar firm kingpin
SolarCity capitalist
Scary fast monorailish-but-not vacuum transport plan originator and champion
Philanthropic patron of folks with a major fascination for AI, apologists for both caution and gusto about it
Boring Company instigator with plans to dig subways in L.A.
plus additional stuff (that guy has had a hand in astonishingly many things...)
But for fact that said individual was said prior, and that I am slightly in a similar domain to him, I would not know which (singular) particular individual half of that points to
This is good! I guess a bit of thought can go a long way toward good workarounds. I'd hazard that it is harder if a taboo glyph is in both particular nouns though.
