I think the difference is that propane torches are an imprecise mechanism generally used to clear dead area between planted rows, while this laser based solution could be used selectively within a planted row (provided it is real at all). Fully agreed about the 3-point comment though. Why take on building an autonomous tractor AND a targeted weed-killer, rather than tackling the differentiating problem only? Seems like a hype train measure. Or the systems integration is very important, in which case a partnership would be the obvious route or white-labeling an autonomous tractor. Regardless, this strategy seems very weird to me too.
