1) if you exclude everybody less than 1 standard deviation above the mean in a normally distributed population, you're left with approximately 16% of the population. The tech sector currently employs approximately 4% of the US population, so at most it's employing 1 in 4 people whose IQ is >1 std deviation above mean. Plenty of room to grow.
2) The idea that STEM education is simply beyond the capabilities of people who aren't in that lucky 16% needs support. The correlation of success in STEM to IQ does not mean causation runs from 'having a high IQ' leads to 'capable of being educated in STEM'. It seems equally possible that 'pursuing education in STEM' leads to 'having a high IQ', and that if we push more people through STEM-oriented education, more people will develop high IQs (of course, that would move the average, which isn't how IQ works, but... you get the idea).
