I don't think lost bitcoins are a big issue at the moment. I doubt all of them will get lost either. What happens when all are coins are minted isn't a big issue right now either. The big things that are in our face right now is block size, total blockchain size and control of core development. I think the latter is the biggest issue facing bitcoin today.
