I don’t think there’s some inherent “dangerous” level of hedonism. If it was impossible to overdose on heroine, no one would have a problem with it. The human brain can only process so many positive chemicals before it reaches a plateau. We’d have to augment the brain itself to both process more of those chemicals and make it possible for us to perceive those increased chemical loads. It might be a useless endeavor, since peaking and returning to baseline is how human brains are wired, and if we keep raising the baseline and peak capacity, we’re just staying the same, relatively speaking. But will it do harm? Nah.

And remember, different cultures see different things as “degenerate.” There isn’t even consensus among the human species on what is and isn’t socially appropriate. And social rules and tastes shift within cultures overtime. Many would say that maximizing the ability for individual expression should be the goal of humanity. As long as you’re not hurting others, let your freak flag fly.

Saying “advanced aliens could do this” is basically just a science “gotcha” headline to get people to publicize their article about how we could eventually do this.

if you wrote a paper that said that humans could do this in the future it would be just as accurate but probably wouldn’t show up in a social feed.

University of Adelaide’s Professor Shizhang Qiao and Associate Professor Yao Zheng from the School of Chemical Engineering led an international team that successfully split seawater without pre-treatment to produce green hydrogen.

Professor Qiao said, “We have split natural seawater into oxygen and hydrogen with nearly 100 per cent efficiency, to produce green hydrogen by electrolysis, using a non-precious and cheap catalyst in a commercial electrolyser.”

The team published their research in the journal Nature Energy.

A typical non-precious catalyst is cobalt oxide with chromium oxide on its surface.

Associate Professor Zheng explained, “We used seawater as a feedstock without the need for any pre-treatment processes like reverse osmosis desolation, purification, or alkalization. The performance of a commercial electrolyser with our catalysts running in seawater is close to the performance of platinum/iridium catalysts running in a feedstock of highly purified deionized water.

Professor Zheng added, “Current electrolysers are operated with highly purified water electrolyte. Increased demand for hydrogen to partially or totally replace energy generated by fossil fuels will significantly increase scarcity of increasingly limited freshwater resources.”

That would never make a difference to me.

Seems reminiscent of the "threads of fate" from "Wanted" (the movie where they curve bullets).

I am hesitant, however, to call the notion outright ridiculous...

My personal take on the theoretical utility of black holes? Blast 'em - find a means of destroying or destabilizing them - there's probably gold in them there black holes...

Autonomous highway driving is a very different animal than autonomous driving in a city. The highway driving is relatively easy when compared to city driving. There's a bunch of other driving situations that have very different levels of complexity.

I just think about how many accidents that I have avoided in the past. There have been times when I just knew that someone at the stop sign was going to blow thru it, I couldn't tell you how I knew but I did. I have seen other instances where I just knew someone was going to do something total boneheaded, again, there were no obvious clues but my brain picked up on them. As humans we process a ton of data in real time, when there isn't enough data, our brains fill in the blanks. We have intuition, I have no clue how you would make any machine have intuition. I just don't know how you could ever program for those kinds of things.

In the end, I don't think that we will ever have a fully autonomous driving system that works in all situations. Yeah, I know, humans do make a lot of mistakes and maybe autonomous cars will make fewer mistakes, I don't know.

A bigger concern is how my autonomous car would make decisions. What are the priorities? Is the life of the passengers top priority? Will my car sacrifice me to save other persons or people? The questions can get into some pretty philosophical/moral areas.
