Im interested to know how long uve been alive so i can evaluate your opinion. If u are still young then its ok to have these strong opinions on the matter, if u are older then u should just be treating these things simply as indicators that increase chance of something being one way or another. U can only judge with the information u have and someone having a phd in computer science doesnt mean they are smart or not smart, but its a considerable achievement and it does mean they are more likely to be a capable person, as there is a bare minumum of intelligence and effort requied. Respect where respect due eh
