There is no way that humanity has figured out all the complexity that billions of years of evolution has created when it comes to animals eating each other.
Corporations are now coming up with new types of 'food' that they can sell for much more profit than the things our species have been surviving on for thousands of years. Take margarine for example - no cows to raise and milk, therefore a much bigger profit margin than butter. They also tell us it's much healthier too. But then studies like this come along http://www.nytimes.com/1993/03/05/us/study-links-heart-disea... , and the whole french paradox, which indicate the opposite may be true.
"When In-Vitro Meat (IVM) is cheaper than meat-on-the-hoof-or-claw, no one will buy the undercut opponent." I seriously doubt it. Even though a grass fed, dry aged steak is quite expensive, many people splurge because they are delicious. Has the author heard of the organic movement growing 20% a year over the past decade? People buying more expensive food because it's healthier and tastes better, that defies logic.
The article claims that this IVM is also healthier for the planet, but it neglects to mention where all the raw ingredients for the IVM will come from. Mother nature already created the perfect way to stay healthy - plants get energy from the sun to grow, animals eat plants, and excrete fertilizer to grow new plants. This happened for millions of years before humans came along. Unfortunately, our farms are no longer run using this perfect natural solution (another issue entirely), but I don't see how IVM would solve this.
My favorite quote from the article: "We won't even choke to death because IVM contains no malicious bones or gristle." It's amazing our species has survived so long with so many malicious bones and evil gristle after us. Malicious bones - I cant stop picturing zombies, haha.
