Fell down another Youtube rabbit hole last night after watching a "Smarter Every Day" video and seeing a video recommended on this channel.

In one video he wants a mural painted on his shop wall, and asks the rhetorical question, "why spend a week painting a mural when I can spend 3 months building a robot to do it for me".
The most interesting to me was the handheld pool cue that doesn't miss.
Once he starts building useful things, we might have way better solutions to things like how asphalt shingle roofs are installed, or laying tile. Seems silly to me things like laying tile is still done by hand instead of 20x faster with more precision by a machine. I've ranted elsewhere at the inefficiency of bespoke structures and finishes in other threads.
