The speaker says some economists answer arguments about explosive growth rates, such as 30% rather than 3% annual growth, with objections about absolute productivity levels.

“I mean, some things that we've heard from economists, like again, there was this argument that like people sometimes respond to our argument about explosive growth,”

“which is an argument about growth levels.”

“So we're saying we're going to see 30 percent growth per year instead of 3 percent. They respond to that with an objection about levels.”
