I'm not saying that there are no inventions. But it is important to understand that there are two kinds of inventions; let's call them "microinventions" and "macroinventions".

Microinventions are inventions that have already been invented. Ordinary things, such as an airplane or an iPod. Nobody sane is denying that microinventions exist. Suggesting that would be committing a strawman fallacy.

On the other hand, macroinventions are inventions that haven't been invented yet. Such as AGI or nanotechnology. By definition, there are no examples of existing macroinventions. Therefore speaking about their possibility is completely unscientific. Your faith in macroinventions is like a faith in Santa Claus.
