That's not too surprising given that this was the planet around TRAPPIST-1 closest to the star and receives 4 times the solar irradiance than the Earth, which is twice what Venus gets.

It's actually the 4th planet from the star that astronomers have the highest hopes of finding an earth-like atmosphere.

Yes radio does lose power when it travels long distances.

I think radio might be the most appropriate for this kind of communication because it should be the first method of communication that technological civilizations discover. That means everybody should be able to send and receive radio.

An earth-like planet with a similar technological civilization would have to be no more than 122 light years away to detect our signals because we've only been using radio for that long. Most likely they'd have to be much closer or the signals would just be too weak to pick out from the background noise.

122 light years sounds like a long distance, but keep in mind that our Milky Way galaxy is over 100,000 light years across. Any other galaxy would be hopelessly too far away to ever receive a radio signal. The closest major galaxy is Andromeda at over 2.5 million light years away.

It's entirely possible there are several radio signals from other planets traveling from planets in our galaxy but they either haven't reached us yet or are too weak to pick up by the time they've crossed that vast distance.

It's not hard to get statistics on how many people were saved by the vaccine. You just look at what percentage of people who die from the disease who didn't get the vaccine compared to the percentage of people who die from the disease who did get the vaccine and apply the difference to the people who got the disease with the vaccine.

You're a SDE for a top tech company. You already have the best overall career.

I'm not sure why someone with your skills can't see that this AI stuff isn't going to have a negative effect on software development. It's like saying we weren't going to need programmers after going from assembly to high level languages. Like high level languages, AI tools are just going to make programmers more productive. They can't be replaced.

To be honest, you'd be crazy to give up being a SDE to ruin your knees or back doing a trade job.

Helion's approach of getting electricity directly from the energy created by the fusion reaction seems intuitively to be the way to go. Other approaches rely on getting enough excess heat energy from the reaction to power steam turbines.
