Not because we’ve reached any sort of technological apex, but because we’ve perhaps reached a point where the capitalist mechanisms for innovation are sputtering.

It's the neoliberal mechanisms. The machine was doing OKAY for tech progress under Keynesian policy. Not better than socialism but it wasn't the crawl we're currently seeing.

The top 1% consumer in the world is basically comfortable at this point. There isnt really a consumerist way of making their lives better. Like you can sell more high quality stuff beyond the top 1% by making it cheaper through process improvements, but its not necessarily tech advancement.

They do want immortality.
