Jobs/Sculley and later Tim Cook situation comes to mind - Sculley had the whole CEO experience but look how that turned out and look at how Tim Cook took over operations part which Jobs had no interest or knowledge of and made it work so well. If they had Tim Cook as the CEO pre-iphone days - I am not sure if we would have seen the iPhone.
Consider the alternative: the CEO is a professional “manager” who can run the shop, but may (or more likely, may not) understand what the shop is all about. Then who drives vision and strategy? Someone lower in the hierarchy can’t get himself taken seriously enough (sorry, but that’s just the nature of hierarchies). He (Atul) could be made the exec president or something of that sort, but an organization like this one needs a more hands-on visionary, who can corral the staff, while leaving the administrative and political minutiae to a trusted lieutenant.
Put another way it’s like giving $100M seed round to a visionary but completely unproven founder when the company is not even at garage stage. Might work out, but seems quite a bit more likely to fail than $100M given to someone who had done something like it before.
