A constant 2% economic growth rate implies that we expect the world economy in 2100 to be 350 times as large as the economy of today.
Check your arithmetic. 100%*ln(2)/(2%/year)=34.66 years to double. 75 years until 2100, so by then the economy would be 2^(75/34.66)=4.48 times as large, not 350.

Oops. 350% growth, not 350X growth…lost some decimal places there. Thanks for the correction.
The thing is, it’s still a huge increase.
