Post-scarcity? Sure, if you live in a first-world country and are upper middle class or higher. These tech-bro pundits have a very limited world view. The basic essentials of life are very scarce for millions and millions of people, and AI will probably make that worse, not better.
Why should AI make it worse? Can you point to any other important technology that historically made people in poor countries even poorer? Technological progress generally lifts people from poverty in the long run. There could be issues caused by disruption of established systems in the short term, though.
