Thanks for the input @justtryme90! I always appreciate experienced and educated responses!

I completely agree with you when it comes to most of the GMO concerns being overblown. It seems most of the concerns come from a place of fear and misunderstanding rather than an educated and researched opinion on the matter. As with most things, people hear that it's genetically modified, and they suspect the worst without any evidence to suggest such an opinion.

Although, I do respectfully disagree with the effect CRISPR will have on GMO's. Now, I openly admit this is speculative, but using CRISPR and Fourth Generation Gene Editing will be vastly more precise and efficient in comparison to TALENs and ZFNs, and other gene editing techniques. At first, I agree that the differences will be negligible compared to current GMO techniques (such as browning), but as the technology gets better (again, there are several hurdles in front of this), the differences will become much more dramatic and noticeable.

As for cancer treatments, I also agree that it isn't so simple as taking a pill -- yet. Again, I'm being speculative here, but with an effective enough delivery system, there's no reason that it isn't possible. CRISPR has already demonstrated an ability to effect expression levels through the epigenome. It's natural to speculate off of that. Are there hurdles? Undoubtedly. But I'm not pretending there aren't.
