What did Alan Kay and Steve Jobs talk about at the 2007 iPhone keynote?
&gt; <i>(the Mac was done in 1984, 11 years after the more powerful and capable Parc Alto, which started working in 1973).</i><p>I find this comment mildly irritating. The Alto apparently cost $40k [1] in (or around) 1973, which was equivalent to $95k in 1984 (or $232k today). Compare with the Mac which cost $2.5k in 1984.<p>Sure, the Alto may have been more powerful, but if it was financially out of reach of almost everybody, it&#x27;s no wonder it had a limited direct impact.<p>I wonder if it&#x27;s a trend that Alan underestimates the importance of economics for technology to actually have an impact.<p>[1] <a href="http:&#x2F;&#x2F;www.computerhistory.org&#x2F;revolution&#x2F;input-output&#x2F;14&#x2F;347" rel="nofollow">http:&#x2F;&#x2F;www.computerhistory.org&#x2F;revolution&#x2F;input-output&#x2F;14&#x2F;34...</a>
