While the tech is useful, the mass amounts of money being shoveled into AI has more to do with the ever escaping mirage of a promised land where there will be an infinite amount of 'more'. For some people that means post scarcity, for others it means a world dominating AGI that achieves escape velocity against the current gridlock of geopolitics, for still others it means ejecting the pesky labour class and replacing all labour needs with AI and robots. Varied needs, but all perceived as urgent and inescapable by their vested interests.
I am somewhat relieved that we're not headed into the singularity just yet, I see it as way too risky given the current balance of power and stability across the planet. The outcome of ever accelerating tech progress at the expense of all other dimensions of wellbeing is not good for the majority of life here.
