The engines are different (electronic fuel injection, timing and compression ratio monitoring), the transmissions are different (dual clutch, torque vectoring differential), the electronics are &lt;i&gt;massively &lt;/i&gt; different, safety features are like out of sci fi (parking cameras, adaptive cruise control, anti-lock brakes, in-dash navigation, ).  All that and the quality (fit &amp;amp; finish, reliability, durability) is hugely better.&lt;p&gt;A typical mid-market car of today would have been considered absurdly high quality and uber-luxurious in 1980.  The difference is night and day.</text><parent_chain><item><author>ClumsyPilot</author><text>I think it&amp;#x27;s obviously waning if you look at any field that deals with physical world: a car from 1940 looks totally different than one from 1980&amp;#x27;s, but the one from 2020 and 1980 looks almost the same.&lt;p&gt;Space rockets are same as they were in 80&amp;#x27;s, where are nuclear engines, fusion propultion, etc?&lt;p&gt;Its the same for airplanes, appliances, and everything execept computers.&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;twitter.com&amp;#x2F;Snowden&amp;#x2F;status&amp;#x2F;1451342274667876353?t=RO7_VrhNEv7nPFCPc20XSQ&amp;amp;s=19&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;twitter.com&amp;#x2F;Snowden&amp;#x2F;status&amp;#x2F;1451342274667876353?t=RO7...&lt;/a&gt;</text></item><item><author>supernovae</author><text>No, it isn&amp;#x27;t waning.
