there's tons of free storage too

I know people are allergic to the word blockchain, but you can store variables on them for nearly free (its a one-time cost), have unlimited free read traffic, and have your users pay to update your state for you

your frontends just read that and update dynamically

cloud platforms aren't able to compete with that, and you can just do system design that is applicable to this infrastructure while scrapping every idea that doesn't work - just like in the before times
