I disagree that the invention of home appliances has stopped.<p>The appliances you list are &quot;labor-saving&quot; devices. But there is only so much labor to be saved. In the last quarter of the 20th century, and into today, new home appliances tend to be for communications or entertainment. Examples:<p>- TV, then flat panel, digital<p>- Computer, then laptop<p>- Modem - telephone&#x2F;Cable&#x2F;DSL<p>- WiFi router<p>- Cable box&#x2F;DVR<p>- Video game system<p>In addition, an entirely new category of appliances was created: the personal appliance:<p>- PDA<p>- Cell phone, then smart phone<p>- Tablet<p>- Fitness sensor, then smart watch<p>I think the next round of home appliances is likely to be energy-related:<p>- Solar panels<p>- Home battery<p>- Smart monitoring &amp; reporting system
