If you come across any once-upon-a-time well-established celebrity who has launched a YouTube channel from a quite a time now, it is pretty clear as day; no one is giving them work offers in the industry.

That's why they'll post shit on their SM handles about the things they don't understand (especially political issues) or pretend to be an intellectual. I don't take them seriously. What about you?

Of course, there are exceptions. However, it is the exception rather than the rule.
