You're imaging like one picture of debauchery is Justin's entire life lmao.
No, I've been reading more about his come up, how he got to the point of making rick and morty, how it started out as other projects and such. Then seeing what he's doing now.
His personality is not going to change as he's what, 40? Work ethic isn't going to change either.
He has without a doubt just hit success and become famous, dude he's literally hanging out with pornstars and going to celebrity parties. You can't really be sure how people are going to react to a sudden immense change in the way they live their life, that's a massive difference from how he was living before rick and morty.
The same could be said for anybody making it big, look at how many celebrities have handled fame, it ain't pretty. He certainly would not be the first person who got a hit tv show or something and then ruined their careers because they didn't acclimate and adjust to the changes correctly. I could go on a list of celebrities that have done this, but it really shouldn't be necessary its common knowledge that power/money and fame does something to people.
You think just because he's 36 that somehow means his personality is cemented in stone and can't be affected by becoming suddenly becoming famous and making lots of money? People go through massive personality shifts in their lives WITHOUT ever having anything as momentous happen to them as Justin or Dan.
Look at him, the dude is a nerd turned huge famous celebrity in the span of about 2 years at most. He's lovable because he seems down to earth and relatable; become famous, add lots of money, parties, (probably) banging pornstars, hanging with other celebs... then what do you get? A not all that relatable guy anymore.
Pornstars are often known to do this kind of thing for money, cause they are desperate. Look at what happened to Charlie Sheen something like a hand-full of big pornstars on the same level as riley reid, took him for all he was worth. Granted that was a mutual thing, I don't defend charlie, dudes a clown. But the example is worth making. Porn-stars are like any other escort, bought and sold woman, they go to whoever can provide the resources for the lifestyle they want.
I think he's shifting into another stage of his life. A period of change certainly. I'm only speculating.
It's just so out there...
No, it really isn't out there to suggest that fame and money is changing somebody. That's kinda petty to try and frame it as if a reasonable thought is somehow a thought crime.
