Summary
50 to 100 years from now, technology will save more than $200 billion per year, because it currently saves several billion per year.
Notable Assumptions
The author establishes a current savings, and then concludes that there will be more savings in the future. She is assuming that the savings rate will increase over the next 50 to 100 years. There are many ways that this assumption could take form, but generally, we need to know that there won’t be anything preventing that increase from happening.
