Medically, we now have drugs that break up blood clots and give heart attack patients a fighting chance if they get to the hospital fast enough.  Same thing with some stroke victims.  Today people who would have died from anaphylactic shock from peanut allergies or bee stings can carry around an Epi pen and a couple of Benadryl tablets and have a great chance of surviving an attack[1].  When I was a boy scout, I was taught the sequence of CPR was ABC- Airway, Breathing, Circulation.  They very recently changed it to CAB, and there were quite a few other things that we&#x27;ve learned along the way that changed how it works.  I understand that the CPR program is changing again at the end of this year.<p>Of course, these change are small and not on the scale of nuclear fission.  But there have been tons of significant medical changes in the last 40 years that increase quality of life and let people live who otherwise would die.  And I&#x27;m not even getting into the changes I consider even more significant medically, or in AI.  Things computers are doing today weren&#x27;t even imagined a generation ago.<p>[1] Epi pens started going out to the public in the 80&#x27;s.  If you have a serious allergy that could lead to your airway closing up, and don&#x27;t yet have an Epi pen, go see your doctor and get some.  People still needlessly die from that stuff all the time, and it can be prevented.
