Now I just think, what a big waste of brain cells.
However, that's not how human brains work. It's not like someone who on an average day spends, say, eight hours doing intellectual work and four hours socializing could do 50% more useful intellectual work by spending 12 hours working instead of socializing. For the overwhelming majority of people, it's impossible to employ their brains productively for more than a few hours a day. You get tired and lose focus to the point where you're just making a mess instead of progress.
Similarly, if you develop skills independent of your main intellectual pursuits, it's not like they will automatically steal resources and make you less productive. Human brain just doesn't work that way. On the contrary, a suitable schedule of entertaining diversions can increase your productivity in your main pursuit.
Of course, there are exceptions. Some people really can spend nearly all their waking hours intensely focused and fully productive, without the need or want for anything more in their lives. However, this is a very small minority, even among people working in math, hard science, and technical professions.
And what do you think of the idea that allies and status were much more important in our EEA (i.e., tribal societies) than today, and as a result we are biased to overestimate their importance?
That argument can be used to deny the importance of absolutely everything you do. Unless you believe that some part of you came into existence supernaturally, or you're carrying some highly consequential recent mutation, absolutely everything in your thoughts and deeds is a result of some impulse that evolved in the EEA (although of course it might be manifesting itself in a way very different from the original in today's environment).
I agree with everything, except:
absolutely everything in your thoughts and deeds is a result of some impulse that evolved in the EEA
-- unless you're using “impulse” in a very broad sense. Plenty of thoughts and deeds (even in the System 1) are the result of your brain's inputs in your life so far.
Followup to: Do you have High-Functioning Asperger's Syndrome?
LW reader Madbadger uses the metaphor of a GPU and a CPU in a desktop system to think about people with Asperger's Syndrome: general intelligence is like a CPU, being universal but only mediocre at any particular task, whereas the "social coprocessor" brainware in a Neurotypical brain is like a GPU: highly specialized but great at what it does. Neurotypical people are like computers with measly Pentium IV processors, but expensive Radeon HD 4890 GPUs. A High-functioning AS person is an Intel Core i7 Extreme Edition - with on-board graphics!
This analogy also covers the spectrum view of social/empathic abilities, you can think about having a weaker social coprocessor than average if you have some of the tendencies of AS but not others. You can even think of your score on the AQ Test as being like the Tom's Hardware Rating of your Coprocessor. (Lower numbers are better!).
If you lack that powerful social coprocessor, what can you do? Well, you'll have to run your social interactions "in software", i.e. explicitly reason through the complex human social game that most people play without ever really understanding. There are several tricks that a High-functioning AS person can use in this situation:
