If you used most types of nuclear propulsion at low altitude, you would pollute the atmosphere. It would make sense to wait until you are past the moon before firing up your nuclear engines.

Chickens aren't that rare outside of zoos. I've seen wild chickens before.

That was an issue with the Addams family movies. The movie producers paid the comic strip artist who created the characters, but they didn't pay the people who produced the TV show. There was a bunch of stuff in the TV show that was not in the comic strip, so the TV show people sued the movie producers and got some money. Gomez had no name in the comic strip; that name was invented by the TV people.

Chickens eat insects and scorpions. If we stopped eating chicken meat, chickens would still exist outside of zoos.

Many humans believe that they know how to hire the best candidate, but they may be wrong and different humans disagree. How would you evaluate AI? How would you know if it is making good or bad decisions? Is the NBA biased against whites? Just because you hire a disproportionate number of people from one group, that doesn't mean that the hiring system is unbiased.

One problem with cities passing laws like this is that cities are easy to flee. If bankers flee NYC, then there will be fewer people eating at NYC restaurants which will lay off restaurant workers. A city can go into a death spiral where it tries to fund everything with fewer taxpayers.

The other issue is random events: meteors, strokes, and murders. If you didn't age at all, you would still die eventually due to random events.

It looks like NASA is hoping that there will be revenue. It isn't clear what revenue there will be outside of NASA. There would be a few tourists, but I don't know how big that market will be. Some tourists would be fine with 3 hours in orbit with no docking with a space station.

This would be the same as viewing the past. I don't know if that qualifies as time travel. When you look at stars, you are looking at their past. Betelgeuse may have already blown up, but we don't know it yet because light from the explosion hasn't reached us yet. It is 642.5 light years from Earth. Holograms are usually visible, so I'm not sure what definition of hologram you are using.

It seems to me that you need to test all forms of memory including being able to remember things that happened 20 years ago. You also need to test intelligence. If you only test one specific type of memory, you can't say that there are no side effects.

France would be better off recommending a younger person. 44 is not too old, but it will be too old in 6 years. A 33 year old who can wait 10 years would be better.

When playing a video from your C drive, it is possible to turn "Replay" on so that the same video will play repeatedly. This means that you could die and people who found your body would see the video still playing.

Aren't 3-wheeled vehicles kind of dangerous? Low-income drivers might be a bit dangerous.

They should have had plastic tubs in back to prevent the clothes from blocking the latch.

I read that they judge distance by focus instead of using binocular vision. Their eyes can be focused for different distances and they know what distance it is focused for. They need to know the distance to use their tongue attack.

The horse thing was proven in the 1870's with one of the first movies.

Many lower income people don't own single family homes.

Now, we need to keep this drug away from farmers. If farmers start using it, bacteria will become immune.

In addition to workers being fired, you also have workers not being hired. Suppose that a company builds a new factory and hires 100 workers, but in the past, they would have hired 300 workers. That's 200 workers being replaced by robots without anyone being fired.

As I understand qualified immunity, you can't sue individuals, but you can still sue police departments. If my understanding is correct, I think that qualified immunity is a good thing, because it prevents rich people from harassing poor people. Trump has threatened to sue many people. I don't know if Louisiana is different.

It is beginning to look like democracy has died.

When Obama ran for reelection, he bragged about killing Osama bin Laden. Trump wanted to do the same thing when he ran for reelection, so he killed somebody. I don't think that he cared that much one way or the other about General Soleimani. Both Israel and Saudi Arabia may have been OK with him killing a Shiite.

This assumes that people won't die. I don't think that Africa's population growth is sustainable.

I buy trash bags, because cockroaches hate them. They are a difficult surface to climb on.

I have a concern that civilization on Earth is sliding backwards. If we don't create space colonies now, we may never do it.

If you offer free housing, a bunch of non-homeless people will apply for it. Many adults live with their parents. If you bought a farm and built a giant apartment complex, they would have homes, but they would be away from support services and jobs. Increasing the population of the exurbs increases the need for roads.

Many people don't despise the homeless; they just want them someplace else. I think that we need to reduce immigration -- both legal and illegal. If you build enough houses for everyone and stop population growth, then you can solve the housing shortage issue. If you increase the population, you have to build both more houses and more roads.
