If you're not convinced - sign up and pay by the token of a high or highest level model. Anthropic or Grok for example. The vendor isn't the concern. The quality of what can be done. Then, find an agentic 'harness' that is written in a language you can read. There are several (pi, opencode, crush, etc) and then clone that repo or one of yours you don't mind having exposed and then point your agent to that repo.
Now ask questions: what api calls are made by this repo? Where are secrets stored and sourced from? Do an adversarial investigation and list the bugs. Then fix the bugs.
Then review the work and determine the value and how to wield this new tool. It replaces reading, writing, and editing - not thinking.
The revelation to me was that I used to code what I know, now I could code what I don’t know. The common path is that when I face something I don’t know, which is quite often, to move forward I have to level up my understanding.
