May I suggest that limitless economic growth is a debatable premise to start from? Have a look at https://en.wikipedia.org/wiki/The_Limits_to_Growth . From 1972, but still worth a look.

We already and always live at the limits. Innovation is pushing those limits further everyday. For example, Internet solved lots of limits related to physical locations, distances, and land areas, electric cars and sustained energy production will solve limited oil supplies, space exploration and asteroid mining will solve limited resources of other materials (if they aren't made irrelevant before that by other innovations). Etc..
