It is outdated. It just requires two clicks.

The video in the article shows them testing with an electric leaf blower.

No discovery is useless. Even if it isn’t used now, it could lay the groundwork for more useful discoveries later.

Just put the laser high enough above the ground, like in orbit, and nothing will ever reach the lens.

Why would people want this? How else do you find videos to watch?

I did. Change is hard but it’s hard to argue that we would be better off without that robotics. It does a lot of work for us and we can all have better stuff because of it. In a better world we’d be excited because it means we all have to do less work but the upper class just keeps finding more stuff for us to do.

How is that worse than the huge amount of money they have to pay for insulin now?

We already have tons of terrifying sounding technologies. Almost every technology can be used in good and bad ways. We could use current gene editing to make super viruses that wipe out the entire world population. Gene editing has also given us the power to make way more food than we ever thought was possible. This new tech could create miracles for people with genes that harm them, like diabetes. Nuclear physics gave us the atomic bomb but also gave us an amazing and world changing source of energy. Staying ignorant of some science just because it could theoretically be used for something bad is never the right way to go. We have to learn everything and try to use it for the most good that we can. Plus I doubt this is something they could just randomly do to people. It’ll probably still be a rather complicated procedure only done in certain situations.
