One of my pet peeves is the idea of asking the world to accommodate a situation rather than build solutions that adapt to the world.

Big example: the best we have for mobility nowadays is a wheelchair of some sort. That requires building special ramps and elevators everywhere.

If we had a four legged chair that could climb stairs, etc, like what BD is doing, it could transport people ANYWHERE. you could literally go for a stroll in the woods with it. People that are injured for 6 weeks in their home could go up and down steps, etc. The elderly could go for walks in a park.

So I for one fully support more research into smarter mobility that doesn’t require the world to accommodate it, but instead adjusts to its surroundings.
