Long before bitcoin was introduced, the idea of blockchain existed. It just became popular with the rise of bitcoin. To make the story short, bitcoin is just an igniter for the rise of a new technology which has a wide range of uses for the financial industry, supply chain, government transparency, and many more. Blockchain will not be known without the creation of bitcoin. It will just remain as an idea and an unpopular and underrated technology. Bitcoin just made it possible for blockchain to be known. But today, with many coins existing in the crypto space, blockchain will never cease even with the fall of bitcoin.
