There's a great book on this called the wizard and the prophet. Might be worth a read if you want to know more.
My personal take is that the risks of high population growth are insanely huge. Science and tech are great. They are far and away the best ways to produce value. But assuming that there will be magical solutions to every problem we are creating is wildly irresponsible, and is part of what has led to this slowdown in population growth. Fishing is harder because we killed most fish and now the price of fish is increasing. We are largely as developed as we are due to natural resource extraction. Fish populations fed early humans but are down massively compared to pre human levels. Almost every single old growth forest is gone. Many species are extinct. There are lines which, when crossed, take millennia or more to recover from. We take way too much for granted. Full speed ahead would likely result in an overpopulation crisis. Give predator prey ecosystem graphs a google. Give Kesler syndrome a google. Give superintelligence by Nick Bostrom a google. We need to slow down actions which may have long term impacts across the board. More thinking, less doing.
Sorry for sounding so scary and dark. It's hard to talk about extential risks without seeming scary. I'm nice in person I swear lol!
