The assessment finds quantum, orbital, photonic, and neuromorphic alternatives too limited to replace conventional AI hardware soon, while electricity connections taking five years or more become the nearer constraint.https://papers.ssrn.com/sol3/papers.cfm?abstract_id=7201180https://papers.ssrn.com/sol3/papers.cfm?abstract_id=7201180Compute Without Concrete: A Critical Assessment of Alternative Pathways to Artificial Intelligence Infrastructure Scaling | Energy.
