We're on Hacker News - a site focused on startup and entrepreneurship. Risky, dangerous, and unsafe are all buzzwords that we flock to.

Yes but you can go from seeing to blind in under a second with these lasers - and anyone else unfortunate enough to be hit with one of these.

It's not only unsafe but possibly criminally negligent to operate this as is shown on that page.

Casually tossing around phrases like "criminally negligent" spoils all the fun of hacking. Seriously. You are strongly overreacting. Haven't you ever been to a laser show? All that's shown on the linked Hackaday article is a DIY laser projector projecting some cool designs. I don't recall seeing any pictures of people pointing lasers at other peoples' eyes.

Further, it looks like this was all done inside of a research lab by someone who knows what they are doing.

Some people prefer a world with sharp edges.

we don't have any laws about amateur usage of green lasers in poland, so if you don't hurt anybody you're fine. last year we had some incidents with people pointing at planes though, but here's not the case.

Certainly if you operated such around random spectators, you'd want to be sure the beam cannot be aimed or reflected at them, but there are certainly ways you could ensure that is so.

The builder on his own, he can do whatever he wants...

You pay too much attention to what your mother told you.
