We are absolutely experimenting with non-text inputs (and outputs as you can see). A big problem we see in mainstream search engines is that syntax is not parsed well. Understanding code as context for the query could be huge for developer search.
Yea true, but its a fine line to something like copilot, since it also can be thought of as a search engine, however it has your whole code (and maybe your past behavior too) as its context, hard to beat.
