Why is it important to adapt and reinvent yourself with newer generation ?

Even though I’m in my mid20s, I still feel like I’m out of touch with the modern society and newer generation. Like nowadays everything is based on technology. I lack so much life skills and makes me feel insecure in ways that I’m not proficient in anything. I lack proper communication skills especially when you have to meet someone who is educationally more professional. Go to public places to get any errands done gives me anxiety like for example at a bank, medical office. This people have so much knowledge and they use special language and terms that I don’t even understand and I end up looking stupid. Don’t know the ins and out of their industry. I feel amazed so many people have strong awareness socials and problem-solving skills
