I'm not convinced that the ABS graph shows that productivity and earnings were closely coupled before or during the 90s. As it says in the graph title, they've set 1991 as a starting origin (setting Productivity equal to Earnings), so it doesn't imply the two were already as closely coupled as they look. They only appear so close because the graph sets 1991 as the common point to compare both axes.
To demonstrate, I've edited the graph to show what would happen if they made that same graph start from 2009. I've done this by copying the orange line up (and colouring it red) so that both lines begin at the same spot in 2009 instead of 1991. And just like the 1991 line, they appear to match each other for a few years - apart from one major dip around 2016, they align very closely for the first 10 years just like in the full 1991 graph.
But we know from your original ABS graph that the wages were already significantly diverging from productivity by 2009. So, I suspect that if we had a longer graph, then we'd learn that wages were already decoupled from productivity in the decades before 1991, but at the very least this graph doesn't imply close coupling existed in the past and shows evidence of regular uncoupling.
Maybe we should use AI to train them :D
Sure. Although like all tools, AI can only help if used properly. It's not a panacea, and it can't replace most training techniques by itself. Similarly, we can't just "use the internet" to train them or "use books" to train them.
I don't disagree at all. That said, I also want to say I'm glad the ABC exists as a state-funded channel, and it's no secret that I'm very critical of the governments who have held the levers. The main reason I'm glad is because without state-funded channels, we see a more-or-less dominance of the owning class controlling the vast majority of mass media in the hands of the mega-rich and using it to pursue their financial interests and fill the remaining airtime with for-profit drivel. The ABC enables creators to create art and educational shows far far more than commercial media does, it reminds me of George Lucas talking about the filmmaking industry and artistic freedom. When the channel isn't desperate to make money, the employees have more real freedom. And like you said, the ABC is still dependent on the government allowing them to get funding, and they often kow-tow to receive it, but it's miles better than having to please a major shareholder board and major advertisers who don't want to be criticised.
As you've described, the ABC certainly has pressures which bias it against neutrality, and you've proposed some good alternatives which reduce these biases.
