I've stopped talking to recruiters in general. I've never had someone reach out because I'm a good fit for the role/company, but I've had a lot where it's obvious that I just ticked enough boxes on their hiring checklist to push me through the pipe. Once I got messaged by a recruiter who was very enthusiastic about meeting "expert Rails devs" and wanted to hop on a call to see if I had any interest in their company. I've never touched Ruby in my life though. I also just started my first machine learning job recently. Before I was even a month into it I started getting messages from recruiters from companies like Microsoft who were looking for "top ML talent" like me. Unless there's an actual genuine interest from the recruiter, I don't think you gain any advantage by responding to them.
