I'm not sure what conclusions to draw from this observation however.
I would argue that it’s not that we’re bad at using tools that we designed for humans, but more that multiple shifts in the tech world over the last 50 years have intentionally (and unintentionally) broken those tools. AI does not need to use the tools at all, it knows the knowledge that the tools gate-keep and it can write code that does the data manipulation that underlies the most powerful software.
It essentially side-steps the whole mess that is the current tech industry (and to be honest a bunch of other industries).
Dogs were used to rotate roasting spits in Britain during the Early Modern era: https://en.wikipedia.org/wiki/Turnspit_dog Does this mean humans were inferior to dogs at the task? Absolutely not. It was just a more efficient alternative based on what was available to them at that point in time.
I think that was always the dream, even in early 20th century sci-fi. It's not a failure, it is a success.
However, in my opinion it's interesting that the dreamers underestimated the difficulty of robotics. Almost everyone thought that the manual jobs will be the first ones to be replaced. Right now it seems the other way around.
