I think that if we're realistic with ourselves, AI will become exponentially more expensive to train, but without additional high quality data (not you, synthetic data), we're back to 1980s era AI (expert systems), just with enhanced fossil fuel usage to keep up with the TPUs. What's old is new again, I suppose!
I sincerely hope to be proven wrong, of course, but I think recent AI innovation has stagnated in terms of new things it can do. It's a great tool, when you use it to leverage that distribution (eg, semantic search), but it might not fundamentally be the approach to AGI (unless your goal is to replicate what we can, but less spikey)
In other words way forward seems to be to put models in loops. Which includes internal 'thinking' and external feedback. Make them use generated and acquired new data. Lossy compress the data periodically. And we have another race of algorithms.
This was the premise of symbolic AI, but this approach seems to have been abandoned now.
