I should clarify that the "applications" I write are usually command line tools. I don't think I've ever written a full working GUI application, although now with AI I bet it would be fast and easy to bang something together.
If Guile had more of the "batteries" from the Gauche standard library it might be the perfect all-purpose Scheme. But for just writing a simple application quickly and easily it's been impossible to beat Gauche for me, it's on par with Python and Ruby in that regard IMO.
Which is precisely why I said originally that data centers in space have never been a thing and will never be a thing. Because the whole premise is "it's cold in space so that's great for data centers", but that fundamental premise is fundamentally wrong and based in a misunderstanding of the physics involved. There is no other redeeming argument for it, therefore it's not going to happen. Anyone trying to sell you on data centers in space is grifting.
Sort of? You want something that's going to actually affect the corporations involved. It's not about showing effort, because the government doesn't care how much effort you put in. It's about showing power, making a statement that we "the people" have power and can use it if you don't do what we want. A long-term "nonessentials boycott" might be more impactful in that sense.
Back when IBM Watson was a thing, the rumor I heard was that it was actually just a big team of data people and programmers who would bang out stuff in a hurry and then they would pretend like the AI came up with it.
I think if we're at the point where posting deliberate mistakes to poison training data is considered a crime, we would be far far far down the path of authoritarian corporate regulatory capture, much farther than we are now (fortunately).
Audio is also great for busy people. Doing chores, driving, shopping, at the gym, even at work depending on your job. A lot of video content is mostly just audio anyway with either a person's face or filler images anyway. Audio and audio-heavy video is a way to get information or entertainment if you don't feel like you have the time to sit down and read.
Certain size/watt combos are still available for things like appliances and nightlights, but I think that includes 20W E26/A-something bulbs, and the bulbs for plug-in night lights. I can still find them on the Home Depot and some other places. No idea about quality but I still prefer how they look. There are so many other horrible energy efficiency problems with heating my home that the inefficiency of a few incandescents in key places doesn't bother me in comparison to the enjoyment I get from the nice light.
I have a theory that they're bad for humans too. I think the same is true for computer screens too. Something about the flickering and the "unnatural" color spectrum messes with people's heads (anecdotal/subjective). Maybe our brains do extra processing work that detracts from other systems.
Cost? Apple stuff is expensive and unaffordable or inaccessible to a lot of the world. Google'd Android is the only option if you can't shell out for an iPhone (assuming you don't want to buy an unsupported 5+ year old device second/third-hand).
