It's an easier life for sure. All of my classmates ahem short of mind live their happy little lives with partners and dozens of kids now, surrounded by same minded friends and family, the same is happening with ex-collegemates, coworkers, etc
The less intelligent you are the simplier life is, you don't really worry about self reflection, your place in the universe or how you affect anything by simply existing. Hell, even your thoughts and emotions sometimes, it's all just a reaction to whatever is happening around you with a blank mind. Your issues are everyday life - what to buy and cook for dinner, what tv show to watch, how to make your kid stop whining for new toys and lie to husband about a headache, so he'll bug off and sleep already (life of a housewife terrifies me on so many levels lol)
Tl;dr evolving was a mistake, let's go back to the ocean and become bacteria
