If where we are now is the ultimate limitation on what we can do then we have two choices - withdraw to circa 1700, or decide not to.
If you expect to grow an economy in the same way as before - with abundant cheap energy which can be wasted - then yes, there are limits.
However I think we have abundant skills and expertise on how to mitigate the limitations in place and continue to grow in the future. In short I choose the "decide not to" option.
After all we have adapted in the past and I see no reason why we can't continue to do so.
This does not mean "drill baby drill", it means lets use our brains more.
Same aim, maybe different paths.
