That guy lon. You know, the spacx guy. Oh yah, why didn't you say so? Musk.

[Programmatic]

I wouldn't say that using a word such as "spacx" is in spirit.

[schoen]

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

[schoen]

I think "had a hand in PayPal, is making cars that run without gas, and wants to go to Mars" is an apt approach for broad public familiarity.

Mars-bound Musk

I am highly in favor of using humorous colloquialization nyms which match anti-fifth-glyph format to point out individuals.

For Musk, ^this nym in particular

[Programmatic]

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.
