Seth Lazar posted that political philosophy has a blind spot because it usually examines static societies rather than radical structural change. He noted that scholars focused on immigration are an exception and questioned whether such change requires democratic authorisation. Lazar who works on AI safety governance and resilience leads the MINT Lab and is moving to Johns Hopkins School of Public Health made the remark while reacting to another idea. The post presents his view as an observation about the discipline rather than a settled conclusion. No further replies or clarifications appear in the supplied lines.
