Pros
Hard to say. Some really good people for sure. Working on the cutting edge is good. It's a toss up really. The positives that shine through tend to be overshadowed by the negatives.
Cons
Lots of exaggeration and inflated egos. Fatigue/burnout of researchers/staff. Strange level of deception and dishonesty for what seems like no reason. Environment can sometimes feel oppressive/negative. Uncomfortable level of vagueness and secrecy for an org like this. People often midjudge each other and there is a lot of gossiping. Seems like an almost unconscious trend of needless compartmentalization/siloing. Waste of resources and lack of productivity. Exploitation of vulnerable people. People often have nowhere to turn for help. Company culture is superficial at best. Frequent collapse of established order. Rapid and dramatic transitions and sudden upsets. Underlying conflict and antagonism among staff. Alienation of talented people. Toxicity. Problem people. Favoritism and neglect are commonplace.
