The U.S. is experiencing a massive demographic shift as the baby boom becomes the senior boom. According to the Census Bureau, more than 1 in 5 Americans will be 65 or older in 2030. The tech industry is catching on. Big companies and small startups are increasingly developing products with older users in mind.
