+# What We Lost When Unix Won
+
+What We Lost When Unix Won examines the design decisions that became invisible once they became universal. Lisp Machines, Smalltalk, Plan 9, Oberon, BeOS — serious proposals for what computing could be. This book makes those alternatives visible again and asks what's recoverable in 2026.
