In an interview with CBS for the show '60 minutes', Jobs' biographer Walter Isaacson says he admired Zuckerberg's zest for "wanting to make a company."
"We talk about social networks in the plural, but I don't see anybody other than Facebook out there...Just Facebook, they're dominating this," Jobs told Isaacson.
"I admire Mark Zuckerberg," Jobs said of Facebook's chief executive officer.
"I only know him a little bit, but I admire him for not selling out, for wanting to make a company. I admire that, a lot."
Isaacson's biography 'Steve Jobs' will hit stands today. He interviewed more than 100 people - Jobs' friends, family, co-workers and competitors for the book which he describes as being "fair."
In the CBS interview, Isaacson said Jobs "was not warm and fuzzy" and "was very petulant. He was very brittle. He could be very, very mean to people at times."
Whether it was to a waitress in a restaurant, or to a guy who had stayed up all night coding, he could just really just go at them and say, "You're doing this all wrong. It's horrible."
And you'd say, "Why did you do that? Why weren't you nicer?" And he'd say, "I really wanna be with people who demand perfection. And this is who I am."
(sic) Jobs was also not the world's greatest manager. "In fact, he could have been one of the world's worst managers, you know? He was always, you know, upending things. And, you know, throwing things into turmoil. This made great products, but it didn't make for a great management style," Isaacson said in the interview.
Isaacson said much of Jobs' attitude could be traced to the earliest years of his life, and to the fact that Jobs was born out of wedlock, given up by his birth parents and adopted by a working class couple from California.
Jobs said he realized he was not "just abandoned. I was chosen. I was special."
Isaacson said Jobs was also a "pretty abrasive, cantankerous character," sometimes did not take a shower for days and was made to work night shifts by his employer video games manufacturer Atari because he smelled so bad.
Jobs was also not particularly fond of money, and despised people who changed after acquiring money.
"And I was like 25 when, you know, we were worth maybe USD 50 million, I knew I never had to worry about money again. And so I went from not worrying about money cuz I was pretty poor to not worrying about money cuz I had a lot of money," Jobs told Isaacson.
"I saw a lot of other people at Apple, and especially after we went public, how it changed them. And a lot of people thought they had to start being rich, so they-- I mean, a few people went out and bought Rolls Royces and they bought homes, and their wives got plastic surgery, and they, and I saw these people who were really nice, simple people turn into these bizarro people. And I made a promise to myself. I said: 'I'm not going to let this money ruin my life.'"
