Yes the internet, dating/hookup sites and social media has caused a lot of people to not gain proper social skills.
Back in the day, families were larger and people had to learn how to engage with others in person. Nowadays u go to a event, people just be on their phones.
Even for sex, people can go to websites and social media just to get it. One guy who cut my hair one time who was 30 with 4 kids by 3 different women said he went on plenty of fish and met a broad who invited him over and had the drinks, weed rolled up, molly crystal ready and all and she was ready. Back in the day, u had to learn how to attract a woman and engage with her.
Times have changed.
