I think he should have given you credit, you were clearly first and he responded to your tweet so he must have seen it! But he might have just forgotten he had the conversation with you about this, while still being more likely to "rediscover" the term since he had heard it before. Maybe a bit aggressive to not reach out to him privately first but in any case pretty cool that you actually invented a term that is now quite likely to be popular :)
The guy is all in on the world's biggest copyright infringement machine.. good luck getting your credit
I want to reach out since I want to express my disappointment regarding this thing you write here:
"I propose we call this vibe engineering, with my tongue only partially in my cheek."
Back in march 2025, you and I had a brief convo on X about this very term that came to my mind "Vibe Engineering":

I also mentioned it in our podcast in April 2025: https://x.com/Flint_company/status/1909946181897044195
Yesterday, I pinged you on X about this "term's paternity" in your thread without any response: https://x.com/pierre_vannier/status/1975579806495293910
You and I met in AI Engineer in SF last June and we discussed for 1 hour (not about this specifically but about AI and all).
At the very least, it could be cool to mention it in your post or newsletter since, I do think this little convo on X + our talk in SF might have just planted the seed in your head for this "invention" of yours...
I don't want to stay in history books but I think it's cool to also credit people when you iterate on their idea instead of just make the thing entirely "yours"...
Best Pierre
