don't you follow the news? Amazon is bidding on nuclear power plants. We will just build more energy sources. We have way too much leeway to go. Also optimizations are being built both in hardware and software. There is no foreseen barrier. Maybe data to do training but now the models have pivoted to test / inference compute and reinforcement learning and that seems to have no barrier except more compute and energy. That's what stargate is, UAE princes building datacenters in France is, etc… it's all in the news. So far, it seems like a straight line to AGI

Maybe a barrier will appear but doesn't seem like it atm
