Thanks for selling it to the pentagon and not to the rock concerts, instead of saving our ears let's fight unextistant enemies!

I can see a few good uses such as communication and more military stuff (bleh) i am nottt going to be looking forward to all the audio ads and random noises one could make. Audios my favorite sense and this kind of makes me sad too see.

You're unextistant? What is that? Is it a special type of gay fetish? Is it a moron trying to invent words? Anyway, you are the enemy, stupid.

[invertedlow]

Well, since the modern definition of virtualy is "absolutely not", then nothing has not been invented yet. That is correct, as something has been invented. I think what he meant to say was almost nothing has been invented because potentially there are more than trillions of things that still can be invented. His own use of the word confirms its current, modern, unwritten, actual definition. Such use of the word is deceiving, as some think it means "like".

Great inventions. Keep on keeping on!

[AirsoftForAus]

Find out what it means to me

[ofdiscordia]
