My thoughts, too. You know the results of your decisions, which would include seeing how someone would react to something you then don’t do. That covers what I would read minds for. Plus getting rich this way is easy without any real ethical qualms: I just win a lottery.
I do admit that mind control is the one aspect that is tempting, but that has so many ethical problems. Sure, it would be an easy solution to certain problems, but I wouldn’t trust myself to not to eventually abuse it. Using precognition to try and solve those problems requires more effort, and thus would hopefully be a damper on it.
If ethics weren’t a concern, then the telepathy seems more powerful. You could know what people would do simply by making an alteration. The time limit isn’t really a limit since the change is permanent: you just make them really want to do something at the time when you want it to happen. Sure, you need to get yourself within 30 feet of a lot of people, but you can control people to facilitate that.
The main issue is very much the ethical concerns for me. I have much fewer such concerns with being uncannily accurate in my predictions.
