…Copilot relies on OpenAI Codex, a natural language-to-code system based on GPT-3…
… The models that it's using right now are ones that were trained by Salesforce, and they were again, trained basically on all of GitHub public code…
I think in the near future there will be a system using directly natural language instead of program code. Indeed, it makes no sense to spend a lot of money on translating such the language into a structured format, when AI can do it automatically. See how AI translators work? Programs are the same translations!
