Is Polkadot going to survive?

I've been hearing a lot about Polkadot lately, but I'm still not entirely sure about its future prospects. Could you please explain to me, based on the information provided in this paragraph, whether Polkadot has a chance to survive in the cryptocurrency market? I'm particularly interested in its scalability, interoperability, and the potential risks it faces. Could you also compare it to some of its competitors in the space and give me a sense of how it might fare against them? I'm trying to make an informed decision about investing in Polkadot, so your insights would be greatly appreciated.
