A corporation optimizes for shareholder value, market cap or some other X related to business/market goals. They do not optimize for global intelligence capability. They do not benchmark the company based on quantitative capacity to meet or beat human capabilities across the spectrum of activities. Corporations focus on one or a handful of market specific metrics where they meet or beat their competitors. Full stop.
You could argue that it would be in the company's interest to focus on general corporate capabilities, in theory giving them a major advantage in the market, but they functionally don't do that, and I would argue can't because that's not what they are designed to do. I think the only major company that might be doing something close is Alphabet, and even they are hamstrung by it.
What I do agree with is this part: Lack of incentives means very little strong AI work is happening
Which is my primary frustration with the field. Most people don't even want to discuss it, let alone try and specifically work on it (even if it means working on subsets which could help lead to it).
I think there needs to be a philosophical MOVEMENT to create AGI. I think it will take that to get there in a short horizon. I think it will happen regardless, but without evangelical AGI proponents it's going to take a lot longer.
