But we've only had to resort to this because the weeds are becoming resistant to the chemicals. This is just gonna cause the weeds to adapt to look more like wheat so they don't get lasered by the robot. Do you want rye? Because that's how you get rye.

(no joke, it's thought that due to early human farmers pulling weeds out of their crops of wheat and barley, rye evolved to look more like wheat and barley, and thus reducing its chance of being spotted and pulled. But eventually, it was so much like wheat and barley that it was a good enough crop to grow and harvest on its own)

If the lasers were accurate enough, it would take a long time if ever. Evolution can only happen if there are survivors. No survivors have a less chance of beneficial mutation. Of course the weeds come from somewhere, so not zero chance.

It's not about the lasers being accurate, it's about the vision system used to recognize the weeds, and rye was close enough to wheat and barley to fool human eyes at least some of the time.
