It's been 10-15 years, and people still don't really understand streaming. "There are too many services" - too many compared to what? I'd rather pay $30 a month to three of five providers for an ad-free service, each of which providing way more content than HBO or Cinemax ever did, than $100 a month to one monopoly.

I'd rather pay $9.99 per month for what Netflix used to be before all the companies said, "I can milk these properties for more money if I create my own streaming service and cut out the middleman."

There may or may not be too many streaming services, but there are WAY too many streaming services owned by content distributors. You can't have any sort of meaningful free market among streaming providers if they're all just providing their own content. You still have competition among content providers at that point, but zero competition on the streaming itself.

This is what the article recommends:

The report suggests measures such as a universal basic income, taxes on meat and subsidies for healthy, plant-based foods.

I wouldn't call plant-based meat alternatives "healthy" unless your idea of healthy is dying of salt poisoning.

Without Apple, there probably wouldn't be ARM.

I was using ARM-powered computers daily when the state of the art Apple still had a Motorola 68k.

Apple was one of the cofounders of ARM (the company) in 1990. It did not create the architecture, though it likely had an impact on ARM6 (ARMv3 architecture) and later. Either way, the ARM architecture probably would not still exist if ARM (the company) hadn't been founded. The ability for multiple companies to design and manufacture chips turned out to be critical for its long-term survival and viability in the cell phone market and others.

Arm (it's not capitalized) chips with power comparable (not to mention better) than any PC mobile-class chip were absolutely new when they made the switch.

ARM (short for Acorn RISC Machine or Advanced RISC Machine) is an acronym, and all letters are capitalized. Arm is something attached to your torso.

Oh, totally. Your shitty Raspberry Pi is completely comparable to a device that performs 14x better than it.

I'm not saying Apple Silicon isn't better than the competition — it is — but that's not a fair comparison. Raspberry Pi's performance is largely because they use Broadcom chips, which stay several generations behind the state of the art. For example, the Raspberry Pi 5 (released in 2023) was designed around the Cortex A76 CPU (released in 2018).

Apple Silicon CPUs in a laptop put the power of a workstation-class laptop in the power envelope of a netbook.

Disagree. They put blazingly fast single-core performance and roughly half the speed of a workstation-class laptop in the power envelope of a netbook.

  • M5 PassMark CPU Mark: (28561 multi / 6001 single)
  • Intel Core Ultra 9 275HX top-end laptop chip (56007 multi / 4745 single)
  • i9-14900KS top-end desktop chip (60511 multi / 4828 single)

They're nowhere near the top overall, but their single-core performance (which affects perceived speed more than multi-core performance, typically) is at the top.

To this day, you cannot find a comparison of a PC and a MacBook that doesn't sacrifice every shred of intellectual honesty the person has,.

You really can make the comparison. Which one is best depends on the workload.

You can have better performance, if you don't mind 2 hours of battery life, and you can have half as much battery life as the MacBook, if you don't mind the performance of a Nintendo Switch.

Yeah, that's about right. But Apple also uses those chips in desktop, where the comparison is not nearly as rosy.

Don't get me wrong, I love my M1 MacBook Pro. The battery life is spectacular, and performance is good enough. But I'd be lying if I said there weren't workflows for which Intel would be better. :-)

Nuclear Fission isn't cost effective ... _unless_ you price in the full eco-balance of electricity production. Then the numbers look significantly different and fission could just be a real thing once again. At least until renewables and energy storage have gained significant portions of the energy mix.

No. This is nonsense. Nuclear fuel production has a massive ecological impact. Nuclear only looks good when compared to coal. Stop doing that.

Comment Re:Food (Score 1) 84

That's IMHO really overplaying it. I don't want to downplay food production effort difficulty, but saying "because we've never done it we can't" is like saying "Because we've never built a 5-meter-tall statue of a puffin made of glued-together Elvis dolls, we can't". We absolutely can, it's just a question of whether one thinks the investment is worth it. And I'm not talking out my arse, I have a degree in horticulture with a specialty in greenhouse cultivation. So much of the "keep the plants alive" systems we already do on Earth - you just need to get them there in an affordable manner.

The primary consumables are water and fertilizer. Nobody seriously is proposing building a colony that can't produce its own water. As for fertilizer, that would start off as an import, but a much smaller import than the food mass. On Earth, open-loop fert systems are fairly common, but they're slowly losing ground to closed-loop where you just maintain the EC, filter the returning solution, and every now and then due a nutrient-level test on the solution and individually adjust whatever nutrient might be lacking vs. the others.

We can consume lots of growing medium, like disposable rock wool cubes and the like, but we can also not do that. For example, it's perfectly fine to grow plants in clean sand / fine gravel - just clean it and sterilize it between uses. Something like pumice is better, though it slowly breaks down between uses. But you don't have to use anything special.

If you do LED lights, you may get a decade or so out of them. You can reduce shipping mass for replacement by going with designs that let you replace just the light boards from them (Mechatronix has lights like this for example), no need to resend e.g. the heavy heat sink, etc.

There's a million random things you use or that can wear out, from cleaning solutions to solution pumps to climate computers and and on and on. But they're not a meaningful import-mass, at least compared to food. Really, the big thing is fert. But regenerating fertilizer from waste (plant waste, human waste) should not be - industrially - immensely complicated. For the metals, burn to oxides / hydroxides, dissolve in acid, fractionally crystallize. You'll always lose some from the system, but we're not talking large amounts. For nitrates, Haber-Bosch is nothing exotic to adapt, and you have easy feedstocks (mining is complex, sucking in gases isn't).

Comment Re:Venus is orders of magnitude easier to colonize (Score 1) 84

(To elaborate about PELs: Venus's middle cloud layer is ~1-10mg/m3, depending on altitude, latitude, and what study you trust (our existing data isn't great). OSHA PELs are 1mg/m3 for an 8-hour shift. NIOSH's RELs are also 1mg/m3 for a 10-hour shift, with IDLH of 15mg/m3. Now, this has the two aforementioned caveats. On the downside, Venus's aerosols are higher molarity - 75-85% concentrated vs. ~20% on Earth. On the upside, the vast majority of the PEL/REL/IDLH risk is from inhalation, which obviously, you can't be doing in any atmosphere in our solar system other than Earth. Dermatitis thresholds are far higher. So again, so long as there's not rain/snow/dew/frosts, and you're at the right altitude/latitude combination**, you could probably spend some time outside in shirtsleeves and a facemask, and feel an alien breeze against your skin.

** One also has to stress latitude, not just altitude, as it's cooler for a given altitude as you get closer to the poles. While Venus's middle cloud layer climate is "similar" to Earth's, it's a bit on the warmer side for a given pressure than Earth's - and because an aerostat rides "down" in the atmosphere vs. its internal pressure, esp. at night when it's no longer being heated by the sun, it amplifies the impact. So if you're going to be living in the envelope, you need to find the right balance between how far you want to go below 1atm and how hot you want to have it be outside. Shifting more poleward helps find a better balance between the two (at the cost of lower sunlight availability for solar power vs. the super-bright equatorial regions). It also shortens your effective day (faster superrotation period). You probably don't want to go fully to the poles, though, because of the polar vortices (though how turbulent they are is still an open question).
