A 'mentor' of mine told me to consider this, and this is what I have arrived at:

Disadvantages
a) Finding a girlfriend takes time, and forces you to do things you normally wouldn't want to do
b) A girlfriend requires attention, so unless you can spend time with her by discussing some useful matters (such as common professional interests/you both spend much time studying some engaging subject such as philosophy), it diverts your attention from far more interesting things
c) Having kids doesn't make any sense for obvious reasons (there are so many of them that even considering this is pointless). Not having kids makes it more likely that your relationship will fail
d) By the virtue of there existing a female privilege, they have been conditioned to act in ways detrimental to you
e) Women that are as intelligent as you are/more are far less common, so it's likely that you will have to spend time on dealing with a retard (nobody enjoys it, so doing this every day with a person that you are in close contact with would be a nightmare)
f) By the time you actually are 'attractive' enough for them to even consider you (since they mostly date upwards), they have already had sex with a number of men, which makes your relationship statistically likely to fail
g) Their hormones apparently have some kind of influence on you, so you are making yourself susceptible to manipulation
h) They are females so you are already incompatible at the outset, as you will never understand some of their behaviors (high EQ, greater connection between the two hemispheres of the brain, etc)
i) Other factors, such as them having stupid political beliefs, that will lead to strife.
j) If it fails, you will get fucked by courts

Advantages
a) Some brain chemicals making you feel good about yourself for having a girlfriend. Not like it's relevant since I'm completely happy reading PDFs on my Thinkpad™.
