The only reasonable explanation for the word asexual being used this way is that people heard it in biology class and didn't have the vocabulary to express what they mean for a different phenomena among humans. Non-sexual (or perhaps 'insexual')seems like a far more appropriate term, as asexual has a more definitive meaning relating to a creature that reproduces without a mate, rather than one who avoids reproductive processes. It's somewhat (though not entirely) similar to the difference between amoral (something that is without morals) and immoral (something that goes against morals).

I suppose fortunately the language does generally maintain the proper idea when speaking about something other than 'identity'. We would typically say, for instance, that two friends have a non-sexual relationship, rather than an asexual relationship (among other differing examples). Asexual is reproductive. Non-sexual is not reproductive.

This is a neat idea, but the math here seems heavily rounded in somewhat weird ways, so it seems like they are vastly overselling the capabilities for the current models at least.

They say 100,000 trees a day based on being able to fire 1 seed per second, but there are only 86.400 seconds in a day, so that's rounded up. Still, their 1 billion number based on 60 'teams' should land them closer to 2 Billion with that number than 1 billion they are claiming. That may be good that they are rounding that one down to be realistic though, as these are "germinated seeds" they are shooting, not saplings or larger, so there is likely to be decently less that make it to a reasonable tree stage than are planted. The number also relies on being able to work around the clock all year long, and doesn't seem to account for the refill and transport times which may be big factors since they claim currently each drone can only carry 150 'seed pods' at a time. Since these are still operated by humans (they mention a pair of operators for each 'team'), I'm doubting they would work around the clock anyway.

That all said, it sounds like this would go a long way towards improving the planting situation and speeding things up at least somewhat. If successful, I could imagine larger teams of more than 60 drones in operation, and perhaps investment into improvements such as larger seed pods, faster drones, or more automation for planting to reduce operators.
