Gary Marcus disputes orbital compute feasibility, citing heat, maintenance, and radiation hardening costs

In a reply to Gavin Baker, Gary Marcus refutes the feasibility of orbital compute. He argues that critics question its economic viability rather than physical impossibility, pointing to heat dissipation challenges, high maintenance costs, and radiation hardening expenses. He also notes that locating compute in space is problematic from a "kill-switch" perspective.
