I find the idea that we are not going to see any more life-changing technological advances quite unpersuasive.  New technology usually comes from scientific advances, and science in many fields is advancing rapidly.<p>I can think of at least four radical technological changes that might flow from new science, ones that would make people of the future look back in horror at at how we live today.<p>1) Ways of curing or eliminating the main health problems we have today, such as cancer, diabetes, heart disease, and infectious diseases<p>2) Doubling the human life span<p>3) Greatly increasing the intelligence of the average person<p>4) Establishing mass colonies in space and moving much of the population there.<p>I&#x27;m sure HN readers can think of other plausible advances.
