The point of the article is that this does not have to be the case, and is not the case for all software.

In a classical computer, every bit of information in the system is in a definite state- 1 or 0. In a quantum system with such definite possible states, what you actually have most of the time of the system in some interpolation of the possible states- so in the quantum computer case each bit is usually in a state a1 + b0, where a and b are complex numbers such that |a^2|+|b^2| = 1.

Most of the time, the 'weight' flows back and forth between a and b according to certain equations over time. When you measure the system- that is, when the bit interacts with the outside world, hopefully your measuring apparatus- you see a 1 or a 0, with probabilities |a^2| and |b^2| respectively.

So what you can do is get a whole bunch of these quantum bits- qubits together, and set things up so that the time-evolution of their quantum state is correlated and probabilistically moves towards something you're interested in. Say you can set things up so the bit array- which, at first, will give you a mere perfectly random bit string on measurement- becomes more and more likely to give you, say, a prime factor, or the answer to some other question.

So yes, the quantum phenomenon is that the bits of the computer are quantum objects as opposed to classical.

I doubt a guy running ship-building is 'bound by dogma'. The consumers are the ones who need to be brainwashed into buying new stuff every 20 minutes; the producers don't need to be convinced into some grand story in order to comply- acting along is in their best interests, it's exactly what they want to do! They can do it, knowing exactly what's going on, with their eyes open.

Yeah. Until we've tiled the solar system with solar panels, fusion reactors, and people, we're not done with local growth. Of course, Earth's surface would be converted first, and you might want to treat that as an externality to be taxed and regulated (as we already do with national parks etc).

Is it? If everyone in a country used FOSS apps rather than paying (in money, data, or letting ads into their heads) for proprietary ones, wouldn't that country's people be better off? And nobody's saying there can't be indian-made FOSS.

Unless you're talking about the government putting its own interests above the people's, which makes sense.

It's not so clear to me that the abbatoir of nature is that great, inherently. You could probably make a decent moral case for wiping out all life on earth, should there be no prospects for it to transcend the bloodbath and disease and botflies and rape and knocking the gazelle to the ground, pinning it as you rip out its living entrails.

I reckon that eventually, there'll be 'lab-grown' meat that tastes better than animal-grown meat, while being healthier.

Humans are omnivorous; we're presumably adapted for some amount of animal protein. Even if meat-eating goes out of style, once there's no moral hazard involved we'll gravitate back to it.

In the end, the geometry does imply that for a given reproduction rate, you eventually reach a crunch where there's not enough surface area of new space to expand to for your colonists, who are proportional to your volume. Being uploads speeds up your rate of expansion, because you could send out seedships much nearer to c and then beam over the digital colonists to be picked up by the infrastructure built at the new system- but digitised people could also reproduce much, much faster than biologicals.

No, there was a sizeable contingent who said that all lives have value and celebrating a man's death was demeaning.

Are you talking about the counterparty taking 'physical' people hostage and torturing them? Because that sort of runs counter to 'everyone is invulnerable and immortal'.

Or about them running sentient hell-simulations for fun because they're a sadist? In which case, yes, that is a concern. If you knew it was going on, you could presumably try countermeasures (up to and including threatening to run simulations that decrease the sadist's utility function, if you know it). Otherwise, maybe engage in trades with other people where you refuse to cooperate with someone unless you both audit each other's hardware?
