You can approach this in one of two ways. One is to ask why and the other is to gather the data yourself and then just draw your own conclusions. From what I've seen and know about Sam Altman the praise he gets is justified but you might disagree. What you'll get from asking is interpreted responses from the data but if you find out for yourself then you can judge pg's response appropriately. This seems like a weird way to get background on someone when there's google.com available.
