The technology I try to love, but admittedly have a love/hate relationship with is medicine.
Our teeth are waaayyyy better (used to be a major life threatening issue), we live way longer, we have phenomenal surgery techniques now, MRIs, yadda yadda.
On the other hand we had rabies vaccines as early as 1885, and a polio vaccine in the 40s-50s, but in 70ish years, no major vaccines/cures. With all our computers and education just none. Very disappointing of course.
