So, considering that the $3400/task system isn't able to compete with STEM college grad yet, we still have some room (but it is shrinking, i expect even more compute will be thrown and we'll see these barriers broken in coming years)
Also, some other back of envelope calculations:
The gap in cost is roughly 10^3 between O3 High and Avg. mechanical turkers (humans). Via Pure GPU cost improvement (~doubling every 2-2.5 years) puts us at 20~25 years.
The question is now, can we close this "to human" gap (10^3) quickly with algorithms, or are we stuck waiting for the 20-25 years for GPU improvements. (I think it feels obvious: this is new technology, things are moving fast, the chance for algorithmic innovation here is high!)
I also personally think that we need to adjust our efficiency priors, and start looking not at "humans" as the bar to beat, but theoretical computatble limits (show gaps much larger ~10^9-10^15 for modest problems). Though, it may simply be the case that tool/code use + AGI at near human cost covers a lot of that gap.
