Sooooooo you’ve got a heart transplant to get into the middle of a dense forest during a war, there’s too much flak for air support, and a vehicle would go at a snails pace.
Would you rather die because technology didn’t advance to allow a robot to be able to run through the forest at breakneck speed because planes exist? Or should we be trying to advance technology at every barrier because there’s other situations where those just don’t make a lick of fucking sense.
There’s obviously contextual situations where a plane and vehicle don’t make sense, but sure let’s inhibit progress for… whatever reason you think you’re making here….?
