Which piece of tech is underutilized?

Sqlite for data science. You can do so much with a few lines of SQL, where people usually write error prone, slow python scripts. Importing CSV or TSV data is trivial.

I think constraint solvers are underutilized. Probsbly because people are not aware of them or don’t think in terms of solving problmes based on specifying constraints.

Seems to me that video game characters (3d humanoids) should find uses outside of video games.

At the uni where I work there is a lot of work on social robots, many of these could be prototyped with no moving parts, only sensors.

Non-template-based code generation. So many tools depend on interpolation and concatenating strings together resulting in terrible-looking and error-prone code. What you want is an API for building and manipulating a concrete syntax tree-like structure. Bonus points if the nodes have type information, which would make things like codemods even more powerful.

HHAST and LibCST are notable examples in the right direction.

NFTs and crypto ledgers. Deadset someone gimme a web browser where the pages are just ledger entries of assets that are NFTs. Gimme dat decentralised multi hosting of said website assets and decentralised hosting of the ledger I can check them with.

Legit. Art for NFTs. Meh. Securing data transfers w peer hosted ledgers and code as unchangeable nft assets. Yes pls.
