Built some log databases and back end frameworks myself with some of the same concepts.
I applaud the creativity in rethinking how back ends should work. Please now do frontends next! :)
"But it's not a fully functioning 2023 Twitter!!!" I think some people miss the point. This is not about hey we built a Twitter clone. This is about a POC for a novel app architecture.
We need to be constantly examining and re-examining our thoughts about the best way to deal with distributed systems, scale, developer workflow. Even inventing new ones.
