My grandfather was, among other things, an AI (artificial insemination) tech. He impregnated every cow in his area for decades.

You don't see a lot of cows get pregnant the old fashioned way anymore.
AI isn't genetic manipulation as we think of it though, just selective breeding from a wider gene pool than would be available without it. This new technology seems like a bridge between the two to me. I'll reserve judgement for now, but the nonpatentability (I just made up a new word

) of the results is encouraging.
Getting back to the tomato thing for a second....I've always picked green tomatoes. You wrap them in newspaper, store them in a cool, dark place, then pull them out and put them on the windowsill to ripen. They taste just as good as the ones from the same plant that ripened on the vine.
