That would be awesome, but we've tried for decades and haven't gotten there with basic if/else. I do think it's pretty plausible that if you combine some very slimmed down models with strong heuristics you could get far though. At the moment I think expense doesn't really matter -- an hour of a knowledge worker's time is worth 416,000 tokens of GPT-4, the most expensive model out there. For llama-2 it's even less time. Unless you're processing truly epic numbers of tokens, by far the most important is whether we can use these things for real.
