&gt;<i>modern art = i could do that + yeah, but you didn&#x27;t</i><p>So? The &quot;yeah, but you didn&#x27;t&quot; about a lot of modern art is different than the &quot;yeah, but you didn&#x27;t&quot; about someone saying &quot;I could be a hollywood star&quot;, &quot;I could win the Tour de France&quot;, etc.<p>In the modern art&#x27;s case, people could totally &quot;do that&quot;, and that they didn&#x27;t only proves that they didn&#x27;t bother.
