Yes cryptocurrencies are one thing but look at the possibilities afforded with having a decentralized, distributed ledger in all areas of life. Having a source of truth in things like law or politics. This would be a fundamental shift for society as a whole not just finance.

Quibble: to me "This is day one" is less about "what market can we get in on the ground floor of and ride a wave". It is more to underscore we are driving the innovation or market and that we are always starting from zero, never too late to change / pivot and we're still aggressively growing everything, or that is the goalline.

That isn't meant to take away from your question. As a developer I'm often focused on leaf concerns. Your question is more about broad strokes and I have to remind myself to think about fundamental changes.

I am in robotics and it seems well poised to grow. There’s a lot of big problems left to solve at the research level but deep learning seems to be slowly knocking down big problems left and right.

I think cryptocurrency is more akin to personal computer. DeFi- the internet.
