Especially when you have someone working on autonomous research agents it doesn't seem that off to lament how much time you can sink into the underlying substrate. In my particular case the work started long before LLMs to make actual research easier, the fact that it can also be used by agents for research is just a happy accident.
But since you seem to take so much offence as per: https://news.ycombinator.com/item?id=47425470 + your dunning kruger remark
then you seem to be somewhat blinded by your aversion to AI assisted engineering, because if https://github.com/triblespace/triblespace-rs is a "shitty vibecoded project", then I don't know what a good project actually looks like to you. That codebase has years of human blood sweat and tears in it, implements novel data-structures, has it's own WCO optimal join-algorithm, cutting edge succinct data-structures that are hand-rolled to supplement the former, new ideas on graph based RDF-like CRDTs, efficient graph canonicalisation, content addressing and metadata management, implements row types in rust, has really polished typed queries that seamlessly integrate into rusts type system, lockless left-right data structures, a single file database format where concatenation is database union, is orders of magnitude faster than similar databases like oxigraph... does it also have to cure cancer and suck you off to meet your bar?
You just seem like a hater.
