tardy

Yes.. And to boot, a language survival estimate should maybe be more than half as long as its predecessor about half the time. Someone writing infra go code may throw out everything but the go within any 10 year period.

It seems very wasteful to me to have a lot of small devices sitting out in the elements, how resilient are they going to be?

Wouldn't a device that travels like a snail along a cable or something, while less glamorous than a self propelled (and navigating) device, deliver a reading for a whole line of plants every day without all of the eroding parts per plant?
