The author writes, “In a clinical trial, a team of doctors found a combination of deep-learning algorithms and laser-imaging technology was as effective as pathologists — but faster — at diagnosing brain tumors in near real time, according to a study published [this week] in Nature Medicine.

And the skeptics who raise privacy and security concerns can be easily drowned out in the flashy spectacle of gee-whiz technology.”
