Attached below is a video in which the self-host first showed a scene in which workers in China used lasers to cut the branches of tall trees, then argued which one was more important: the invention or the application of a new technology.

FYI, several years ago when I was in the Bay Area, one day I witnessed a powerful process of cutting branches with a set of powerful machines, and I jotted it down:

QTE Yesterday morning, a juggernaut towing a trailer drove in to park alongside the curb of the house just next to mine. It came to trim the branches of the gigantic tree in the middle of the houses front yard because the branches, twigs, and leaves of the tree have grown so thick that they have almost covered all of the house.

Lets see how to trim a huge, tall tree with machines. The driver got down from his high-level seat, got himself into a gondola controlled by a remote, and raised him up to every position he wanted to reach. He cut the branches with an electrical saw, and in less than half an hour, he cut down all excessive branches onto the yard and the alley beneath him. Then I saw him using his phone to call in a helper, with whom they collected the branches and put them into the trailer, which was actually a stirring machine. The roaring machine soon smashed all of the broken branches into dust and ashes and conveyed them to a big gunnysack through a pipe.

That was what the machine did within an hour.

P.S. Almost every single house has trees planted in its front yard here in the American residential area, even if they are small ones like the apple tree and the orange tree in my daughters. UNQTE
