My best guess is that life is quite common in the universe, it is usually based on similar biochemistry to life on Earth, but it is only rarely as advanced. However, I could be wrong on any of these points.

In particular, we don't know what it takes to get life started. It might be that the watery habitats like those on Titan often have primitive single cell life. The conditions needed to evolve to higher lifeforms are only slightly better known, but it took a long time to get started.

So life on Titan is certainly possible. It may be simple, but perhaps we will be surprised when we finally get some probes into its deep oceans.

Whether life is always similar to Earth life and requires Earth-like conditions, or can appear in different forms almost anywhere, is a huge unknown. I think exobiologistes are more open minded about this than you give them credit for, but there is good reason to think that very hot or very cold environments will be less promising, especially for more advanced lifeforms that we have a chance of detecting.

Yes because that was the answer that it got from its training material. If it had been fed with mis-information saying that votes were stolen it would tell you that instead. It does not have the ability to weigh up evidence and reach its own conclusion, but that will probably be possible soon. Of course many people dont have a very strong ability to do that either.

ChatGPT is not yet smart enough to spot fake news. The people who trained it went to a lot of effort to avoid it supporting anything controversial. The material used to train it must have been filtered to remove anything that would be considered fake news by the people who control it. Other bots in the near future will be able to reason more independently, but we will have to see if these will be allowed to be released to the public.

(1) It's far too expensive (2) It's far too dangerous

Can sell it as green steel at a premium. Companies will buy it so they can sell their products as green. The rest of the world will catch up. No use waiting for international agreement.
