Developments in the physical world take longer than in software. A lot of things are overhyped because people don’t understand the difference between a controlled experiment and a finished industrial product. But it’s not because the hype decreases that we won’t find uses in the future. So yeah, graphite was overhyped, pretty much like high temperature superconductors or other scientific fads of the last 50-odd years. This does not mean that we will never get anything useful out of this (high temperature superconductors found some use cases about 40 years after they were cool and new; there are many other examples).
