I'm significantly older than you. I started coding in the late 60's
Yeah, appeal to tangentially related experience, age and arrogance aren't a way to inspire confidence in your work.
We live in the perfect times to display that experience, age and arrogance haven't been working in almost any field, from politics to LLM development. We've yet to witness any system that operates well, while also eliminating human oversight. It doesn't matter the guard rails you put in place. They're only as strong as your personal ability to evaluate your own product, which itself is a conflict of interest.
Edit: Also, you can't use your own credentials to assert the integrity of work you aren't even actually doing yet passing as your own.
