"Stefano's involvement has been phased out gradually, he did a massive part of the original code for ACC but by this point his fields were broken up and taken on gradually by 5-6 different developers, either from the original team or relatively new guys like Fernando. It is very telling that it required a small team inside KS to take over his role."

Well, it always takes more people when you want to divvy up someone's work, even if they're just as capable.
There's a lot of overhead in comms & documentation.  A LOT.   
The bigger the team, the lower the productivity - in smaller teams, it's really bad.  Add an extra person to your 1-man team (on a single project), and the overall output will be way lower than 2x.

There's also an interesting thing I've read somewhere; reportedly, MS programmers used to write a line of code a day on average.   They had thousands working on the windows code.  I know it sounds really incredibly low.   I wrote a 20k+ line program in a year - alone.  At least 75 lines / day (counting 260 workdays) if you look at it that way.

What a real pity he sold AC. Imagine now if he made it open source.

I hope he goes and makes AC2, something that interests more than the half a dozen Blancpain fans world wide

I have a feeling that he wants to do something completely different from racing sims altogether.

I doub't he could make another racing sim for 5 years even if he wanted to, No doubt when he sold up they would of been a clause in contract forbidding him from making another racing sim, Also the new company would more than likely own all the IP.
My guess is he sold but then stayed on for a bit to smooth out the changeover as he wanted out of sim racing coding

He said "At a certain point I started to feel like I had nothing more to give to the SimRacing genre and it was time for me to go look for new inspirations."
and
"We only have 1 life to live and I am want to make sure I'll use mine to the fullest even if that means starting from scratch and trying something out of what became my comfort zone in SimRacing."
