Do you know what kind of person Tavis Cline is? Collaborating with someone like this is truly a disgrace! Check out this report: https://www.globalcryptoreporter.com/nvidia-engineer-at-center-of-8-million-crypto-scam-tech-giants-name-exploited-in-ai-driven-fraud/

i came to know about this project from langchain. Then i saw the stars on this repo. I have no idea about the person you are talking about

[amritsingh183]

plus, I am doing this for myself and for the open source community and not for the person you are referring to

[amritsingh183]

and obviously i don't go on github and research about the project owner or maintainers. So in context of your comment, "would be a disgrace, if you knew about it", would have been appropriate as compared to "is a disgrace"
