They've been saying Moore's law is dead for 20+ years. Reasons usually quoted for Moore's law's death are quite narrowly focused on a particular technology stack, whereas semiconductor fabrication happens on a complex web of technologies all moving forward with their own S-curves.
It is worth watching Jim Keller's lecture at UC Berkeley literally titled "Moore's law is not dead". He talks on a different level alltogether and far more convincing than the pedantic look at the details that enable Moore's law.
