Most algorithmically generated content is... not worth paying for. Of course, 'in the future' AI will get better, and AI slop will disappear, says the man who's invested heavily in AI systems.
Much stock market and sports score reporting has been generated for years. That works when you have regularized inputs and narrow outputs. This is 'convert this table to text in pre-defined paragraph formats' and not that complicated. Will AI tools help content creators? Sure? Will it make content creators go away? Some. Others will use AI tools to generate even more content.
As for no-human-in-the-loop podcasts/YouTube channels? Those audiences of ten people that marketing f***wits are convinced will be 'microtargetted' consumers / voters are likely to be 90 per cent bots. It'll just be a huge waste of electricity.
