"Holy cow... you actually think that?"
No. I spent years in the pharmaceutical business and years learning how drugs are discovered. The major pharmaceutical companies do not simply find a drug, test it and put it on the market. They look at the problems from drugs and develop strategies to overcome those problems with each new drug.
Do you really think that after aspirin was developed that it was an accident that someone came up with tylenol? Do you think the same of all the different anti-biotics? Most drug manufacturers looks several decades into the future, as well as, the less distant future in determining the path to finding new drugs.
