How was Ken Kutaragi arrogant during PS3 gen? Overly ambitious with Cell to some extent? Yeah. But that infamous "two jobs" quote is actually not the way people remember. The way he actually said it was more in the way of someone seeing buying the system as worth doing even if it meant working harder to get a bit more money to buy it. He never said it in an arrogant way like, how, Don Mattrick did about military people on submarines without internet access. That was an arrogant response.
Outside of that, there are quotes of Kutaragi being a bit blunt with Hayao Nakayama at Sega before the PS1 & Saturn launched, but IIRC they were golfing buddies and I guess the words were exchanged in a way a friend talking a bit of smack would say them, but now pretend these are middle-aged men. Honestly outside of the Blu-ray stuff I don't understand why people call PS3 the 'Arrogant Sony' era; there are no quotes actually said by Kutaragi & co. belittling gamers, and the PS3 itself was packed with a ton of tech making it better value for money than the 360 (considering all the add-ons you had to buy for a 360 to provide the same experience as PS3. Even then you lacked some things like a SD card reader).
Sony got overly ambitious and paid for it, but I don't think any of their choices with PS3 were just them coasting off PS2's success.
