How do you view the 996 phenomenon, and what kind of experience does the 996 work mode look like?

Went for a haircut today and the barber asked me what I was doing.
I say IT.
He said, that should earn tens of thousands, right?
I said that there should be tens of thousands of people who have worked for more than five years.

Then he asked again, did you get off work early?
I said, no, we are 996.
He asked, what is 996?
I said, 9 am, 9 pm, 6 days a week.
He thought for a second and said, isn't this the same as us? We are 10am, 10pm, 6 days a week.
I thought about it for a minute and said, yes, we actually learned from you.
