Don't make the mistake of thinking because there was hype that everything was wrong. HN seems to have a lot of posters that run logic in a boolean manner. { if !perfect then false }. The world is a far more complex place than that both naturally and intentionally by human will.

And the internet has devastated many past businesses that were highly profitable. A great many things in the world look vastly different than from before.

>people were talking as if profits and revenue didn't matter.

People say all kind of dumb shit too. If for example machine intelligence took over the world tomorrow and turned all of humanity into meat cubes for biofuel said intelligence is still going to apply the basic laws of economics to what it does. It needs to have some way of accounting that fact we live in an energy limited universe. Just because economics still applies doesn't mean that we as humans shouldn't be really fucking careful creating said machines as we don't want to end up as biofuel.
