One possible future is stagnation: we’ll reach the economy’s “maximum size” and growth will essentially stop.
This might be worth rewording for clarity.
In the stagnation scenario the economy will not reach the “maximum size” permitted by the laws of physics (using a given amount of matter, e.g. the solar system), so saying “we’ll reach the economy’s ‘maximum size’” is confusing and could easily be misinterpreted. (I understand you’re using the phrase “maximum size” to mean “the largest size that it actually reaches” but I imagine others could easily interpret it to mean “maximum size possible.”)
Suggested rewording: “stagnation: growth will slow and stop before the economy reaches its maximum size, i.e. before the economy reaches the limits of efficiency given the laws of physics.”
