What’s the deal with Rare Earth Metals right now?

I've been hearing a lot about the rising demand for rare earth metals, especially with the push for green technologies and electric vehicles. I'm curious about how everyone else feels about investing in them. Are they worth the risk, or is it all hype? I know there are concerns about supply chains and market volatility, but there also seems to be a lot of interest from big companies. I've been watching some stocks but wonder if anyone has actual experience in trading these metals. Any insights or personal stories? Should I be looking to invest now, or wait for a dip? What do you think?
