This does seem to be a big revelation to ML/AI types. I was at a conference last year for NLP and one of the data scientists was reporting back on some other conference they'd been to where they had worked out that you don't get better performance by running your data through a dozen different models, but by running better data through a single model.
I guess @garyyo@lemmy.world is right that you need to confirm these things but it definitely spoke to quite a naive mindset.
Err how many quests do you make someone go on before you'll sleep with them? Because for me, two very dangerous quests involving swords and magic would be plenty.
