My wife has celiac disease.
Gluten free wheat will never replace normal wheat. However, this is great news for my family. If they can come close to making a gluten free product that tastes similar to “normal” food, great!
I would expect that there will be a very limited market for such wheat, and segregation issues will be a major problem as well. But... We will pay a healthy premium to buy this product if it makes it to the market.
I HIGHLY doubt any of you have anything to worry about in regards to gluten free wheat over taking “normal” wheat as the norm.
And you are correct, gluten free will never take over traditional wheat. If for no other reason than some troublemakers will keep the old stuff around, and plant a small plot. Like I do. ;)
