They can talk all they want (and with AI) but the reality is that people grow things and save seeds. I'm a seed saver. We trade with other seed savers. There's no way to stop that.

A lot in my vegetable garden is seeds that fell from the last year's crops and then grew. More are just seeds from overpplanting that I cleaned, dried and saved and reused.

As far as grapes are concerned, you just have to get a cutting and root it. Easy peasy.
