Kudos to them for thanking the actual people who did the hard work of saving his life rather than some supreme being. Prayers are fine, but first responders and trained medical personnel are so much more useful.

Why would you conflate plentiful with cheap? It's not like we'll all have a Mr. Fusion.

The production and distribution of power will still be a controlled and finite resource.

Not disagreeing, just clarifying. You could look arbitrarily into the earth's past from our reference frame on the planet by viewing it from any distance as long as you did not travel from the earth to get there. When I saw the word travel, that is what I was referring to. If you left from the surface, you could never see anything that happened before you left, no matter how far nor how fast you traveled. That was my point. Which, in retrospect, was not the point you were making.

I don't think this is accurate. To see the light from the past, you'd have to travel faster than light to get ahead of the current wave front. No traveler starting on the Earth's surface could ever see it at any time previous to the date they left unless I'm very much mistaken.

Genes that may have helped you survive the bubonic plague centuries ago became more common in the genome because of that protective benefit. Today, those same genes may be partly responsible for a hyperactive immune system that causes auto-immune diseases like Chron's.
