Resolves 2028-02-01, based on my vibes from the coding I've done in the last month-ish. Resolves YES if any copilot exists that "feels like pairing" and costs under $50 for me to try for an hour.
Things that would make a copilot seem more "pair"-y to me:
voice I/O rather than text
asking intelligent clarifying questions
pointing out potential mistakes I've made, or better ways to organize the code
displaying some knowledge of the broad invariants of the system not obvious from local code analysis
Things that seem like "smart autocomplete":
its main contribution being suggestions for what to type next
being able to extrapolate long function bodies by gluing together code that already exists scattered around the code base
being able to do clever type-system constraint-solving to figure stuff out
