Crazy scientis type villain has definitely undergone a major change in the Elon Musk era. Socially inept, balding and scrawny types appear antiquated. Current popular culture mad scientist is fit, charismatic and most likely stinking rich. He can give a good speech about the solid ethical foundations of his work, although he then invariably slips to the dark side. 

"Beyond good and evil" is a mad scientist trope, but I find this Musk-inspired scientist type to have more understandable motivations than villains usually. Starting out with the noblest intentions, but being blinded by one's own intellect and arrogance makes much more sense than villains that just want to destroy and/or rule the world.

Carlton Drake from the movie Venom, Natham Bateman from Ex Machina, and Niander Wallace from Blade Runner 2049 should arrange to meet. Perhaps they could pool resources and balance each other's ethical blind spots to actually manage to do something good.
