That's more satire. Parody can take the ball and run with it as far as it chooses; satire can only be relevant if its characterization has a degree of verisimilitude.
In addition, the target audience of the show are unlikely to know very much about the valley. I would expect most people believe the valley is "kids from Harvard who think they're hot shit, trying to get rich doing something useless".
Actually, I'd say that's more an in-valley appraisal. I suspect non-tech types would simply view SV as computer nerds finding ways to make millions. Now that Jobs is gone, the industry is dominated by nerd CEOs. Ballmer doesn't count.
We have, in the Valley, a preponderance of companies started and run by nerds. I suspect that reality has leaked into the public consciousness.
If you are in DC I highly recommend the tasting menu at Sushi Taro. Very similar experience to the film - 10 courses of amazing food (although it includes some non sushi items as well).
