Monkeying with nature

What happened to my America? I encourage the advancement of technology. I support stem cell research for the purpose of curing diseases and the like. However I was recently made aware of scientists injecting human brain cells into monkey fetuses. This I do not agree with. 
Now I don’t know what will happen with these monkeys. They may turn out to be amazingly intelligent, or they may turn out to be a bunch of water headed retards. Could this create the missing link that science has been searching for? Perhaps. But what are the ultimate ramifications of screwing with nature? Evolution is real, we’ve seen it in action, but evolution is a natural occurrence free of direct human influence.
 
The debate is that scientists will create a race of humanzees that have the ability to properly communicate with humans. They will be able to perform odd jobs and ultimately become a functioning member of society. If that happens what will the Mexicans do? Could you see a truck full of monkeys pulling a trailer full of lawn equipment come flying down the road. Maybe a cable van comes pulling into your neighborhood and about twenty monkeys go pouring out of the van and begin rushing into houses installing cable television, whether you want it or not. I guess things wouldn’t be all that different than they are now.
 
Seriously though, this is the ultimate Pandora’s box. Forget the whole fucking with Mother Nature thing, what about the civil rights attorneys? I’m willing to bet there are hundreds of lawyers salivating at the thought of imposing civil rights legislation for monkeys. Monkeys would be able to vote, drive cars, date outside their species, or even run for political office. Planet of the apes anyone? Just the thought of a talking monkey is a bit creepy to me. Sure, I’ve looked at my pets and wondered what was going through their little heads. I have a cat that runs into the room every time I get up from the computer and she will cry at me until I follow her into the kitchen just so I will stand there and watch her eat. I’ve often wanted to ask her why it is so goddamn important that I be there while she eats.
 
I can tell you what a cat would say to you 90% of the time. “If I could use the can opener I’d be burying your cold dead corpse in the back yard like it were my last bowel movement.” Dogs on the other hand would be a whole other story. 
Dog: Whatcha doin? Why? How come? Why? What’s that? Why? It would be like having a two year old. You’d leave the house and realize that you forgot your car keys, so you go right back inside to get them and the dog would say, “Oh dear god where did you go? I thought you were never coming back! Where did you go? Why?” Where as the cat would say, “Hey! Get your bitch ass in here and feed me! I can see the bottom of my bowl in one spot.” I don’t want that kind of pressure in my life. I love animals but goddamn it, humanizing animals is going too far.
 
Which makes me wonder, what would a monkey with human brain cells say to you? Where would it stop? Surely if it were successful someone would try it with cats and dogs, and dolphins… What implications would that have on the world as we know it?
