But then you have to pay hundreds of USD for an iPhone (or maybe one hundred for a compatible Android phone) and hundreds of USD per year to upgrade from voice-only cellular service to smartphone service. Or what am I missing?

That most people already have a smartphone.

The data plan issue is a bigger one, I think.

Objects cannot move relative to each other faster than light but the space between them has no such restriction. Hyper Inflation lasted until the universe was about the size of a basketball. The big bang didn't end with (hyper) inflation, it is still happening and the universe is still inflating. The boundary to our modern universe is expanding away from us at the speed of light. So, two observers on opposite sides of our visible universe will be speeding away from each other faster than light. Only an observer in our position can see that the two observers at the opposite "edges" existing simultaneously.

Big fan of Starts with a Bang for many years, I must ask Ethan why cosmologists have ruled out the idea that our universe is the interior of a black hole. Neil deGrasse Tyson claims Einstein's equations can be interpreted to mean there is a different universe inside a black hole but he doesn't elaborate. If anyone else knows of a good reason as to why our universe can't be the interior of a black hole then I'd love to hear it.

Yep, and no matter what you think of Edison, the modern research lab was primarily his invention. A modern lab tends to know what it is looking for (eg: practical light bulb) and is all about the finding the steps to get there (trial and error), compared to say Newton who mainly followed his own curiosity. The trick to being a lead researcher is finding a rich problem space for the students to work on that will attract grants.
