Why are 17 year olds giving career advice?

I am noticing a very toxic thing going on here. I notice a user giving advice to someone about to graduate or is in college who wants to work a high-end job. I get very intrigued, I click on their profile and their most recent post is advice about either "Where should I attend college?" OR "What should I major in?" This is hilarious but also very sad at the same time.

1) All you kids who are just starting college, you are nothing. You havent taken a college course yet you are throwing around "maintain a 3.5" or better yet "I can definately get a 3.8+." Don't tell other users to major to double major in Comp Sci & Economics becauese it is quantitative. Come back when you have taken a Calculus 1 or 2 course.

2) Please don't bother people on LinkedIn. I get very irritated when a 17 year old who hasnt taken a general education course is asking me how they can prepare for an internship. I understand if you want advice but for the love of God you are not entitled so quit hinting you want to intern for our firm.
