This is completely silly. I'm going to give some silly answers. I'll assume that these are male stereotypes, but only because I don't know enough female engineers to extrapolate humorous traits. #1 has no social life, grits his teeth constantly and will probably get grudgingly, angrily married to an unwitting research assistant in his 30s/40s after wondering (for a period of no less than 20 years) why stupid people exist. No children, or an over-worked prematurely-balding vicarious living vehicle, will result. Self-perpetuating cycle. #2 has a weight problem, and will probably sink into a muttering pile of self-loathing in his late 20s, only to rise again as a slightly-douchey fitness freak or a committed family man. He will marry, be quite happy in mediocrity and become a bearded old programmer. Lots of kids. Weirdly, this one is most likely a gun-toting Republican. Kids will most likely be a bit less incurious, which will make him proud. #3 is cool and I want at least one on my team, but because he's a lone wolf by definition, he gets uncomfortable easily. He's most likely a man of at least a couple vices. Has a billion hobbies and a pile of old equipment. Least likely to be academic, which is at odds with his vast knowledge. Simultaneously happy with the present, but haunted by a hope for what could possibly be. #4 also looks on Google for answers, cuts corners at every opportunity, is a great engineer because he conserves all possible energy. Marriage is unlikely, but will probably be an okay father if he manages to stick around for longer than 10 years. Least likely to manage the money he makes without a stickler for a wife. I'm happy knowing all 4 types. I'm happy being a 3rd/4th hybrid. This really scans like a palm reading, as does the question. ("Will I be rich? Will I have love? Will I have children? Is that a good thing?")
