"One guy proposed my friend that he has a startup idea to use GPT-model to let people talk to their pets and that it should be 'fairly easy' to finetune from an existing model."

- haha this is hilarious!!

A younger me once thought, like the person who pitched that to your friend, that all I needed was an idea (..and if only I could find someone to build it...I'd be a huge success!!) and as I matured and got experience in the world, I realised that ideas are cheap and execution is hard. We need more doers! I'm a reformed ideas guy.
