What's the point in writing a profile summary?

What's the point in writing a profile summary if all the information will be useless and forgotten once I have passed? What is the point in writing a profile summary if I could conjur up false statements and produce incorrect info, all within a few key strokes? What is the point in writing a profile summary, if this profile is to become defunct on the day I die?

No one will remember me, nor this Steam account for it is just another cell concealed with other cells. One day Steam will close and with that, it'll take all of my hard-earned work with it. So, what is the point in investing work and time into a digital software? Will you pass it on to someone else, or will you leave it to gather dust like all the others?

I'm not going to write a summary because who's going to remember an individual who sealed himself inside of his little chamber, playing games and making friends through digital entertainment? Who's going to remember someone who's always inside his house and sits in the corner of the classroom? Who's going to remember that one person in the background of an Instagram post, who was never suppose to be there in the first place?

No one.
