When you were born, I was still in my 20s; so were Madonna and Michael Jackson; Brad Pitt was 25 then (he just turned 50 - the jury is still out on whether you are good at math or not). Now, I run to you to roll time back and see people who witnessed your birth being young and alive - you keep them all and more inside your multitude of brains.
In only quarter of a century that flew by with incredible acceleration you have spread yourself wide and deep, becoming the source of memories, reference, entertainment, political battles, nationalistic agendas, and all kinds of freedom fights. Just like other immature tech moguls born in the eighties you strive for world domination without any care for what you have and will destroy on your way to that lofty goal. Just like them, you carelessly offer your services to those who uphold personal liberties and those who do whatever they can to extinguish them.
Talking about mixed emotions! On one hand, it seems that I cannot exist without you and I don't even want to remember how I managed, oh, so many things before you were born. Hey, you gave me this very outlet of self-expression! On the other hand, I think you are a source of some major-scale evil; you made everyone more stupid; you will accelerate further retardation of minds and degradation of humanity - all before you exhaust your own source of existence (aka energy) and bring life functions that rely on you to a grinding halt. So, as much as I need you, I still keep my Britannica; I still buy hardcover books, CDs, and Blurays; and I still write checks. I use you, but I don't trust you.
What can I wish you on your 25th birthday? What can you wish anyone on their 25th birthday? To become a mature and responsible adult. You go and figure out what it means. I still didn't.
