But if you kill your father, get caught and the jury sentences you to life without parole?

Though if the father or the son is awful enough for the son to even consider killing him, this may still happen even without the father being immortal, especially if the father is not very old.

As for waiting forever - long term schemes could become more useful. Invest some money that your father gave to you and 50 years later you may be very rich too. Though asking a 30 year old now to wait 50 years is a bit too much, but if the 30 year old was immortal...

The rich guy will always be able to take his cake and eat it too.

Depending on how rich. If the top 1000 people manage to bribe their way into keeping their ability to reproduce, that most likely will not cause overpopulation. Everyone else will either breed or live longer.

Juvenal already advised wealthy parents about the risk of saying "One day son, all this will be yours", since this clearly shows what is taking them apart from their fortune.

I imagine this saying would stop once the parent knows he can become immortal. Also, being immortal means you can wait longer for something.

Obviously the laws would need to be carefully designed for the edge cases, but I do not think that adoption should affect your status in any way (by adopting you do not increase the population).

But saying that, say, I(and everybody else) should die of old age (I do not care about having children, so I would be the first to sign up for the drug) just because you or someone else want to have children is also unfair. In my (biased) opinion, it's more unfair than saying that you can only become immortal if you do not have children and by becoming immortal you lose the ability to have children.

There are a lot of rich old people who do not want to die (so they are funding the research into life extension). Let's say some scientist discovers the drug. Do you make it illegal for everyone to become immortal and if someone still manages to get their hands on the drug, do you kill them (if so, do you kill them immediately or at the age when they should die)?

Also, how about this: the drug/whatever that cures you of aging also makes you sterile. Or it could be a legal requirement - want to not die of old age? The price is X dollars and your ability to reproduce.

As for the morality - morality changes when circumstances change. Some years ago it was moral to have children work in factories, now it is not. Now it is immoral to tell someone to not reproduce (and leave a legacy), but if the person is immune from aging, then telling them to not reproduce may become moral.

Or a one-child policy not only in China, but also elsewhere where the aging cure is available/affordable. People are still going to die (accidents, murder, suicide etc).

Wouldn't it be cool if anything that used power had to first request it similar to how it's done in USB

No. The USB spec is already a PITA for stuff like battery chargers or power supplies (though I guess just requesting the max power available works). Also, quite a few USB devices do not meet that particular spec, just having the power pins connected (since it's cheaper that way).

What if the device requested low power but used more power?

Also, what about all current devices or DIY stuff? Will they all need to be connected using a converter? Why? The current way the circuit breaker works (too much current = disconnect) is good enough.

So, you will not want to use any device that has a line frequency transformer in it (like, say, some audio gear or pretty much every old device).
Or any device that has an AC induction motor (AC, fridge, table fan).
Also, you are willing to modify the power supply of your PC to work on DC (so the PFC circuit no longer needs not only AC but AC that is similar to a sine wave).
Also, you are willing to use much bigger switches and circuit breakers (to safely disconnect 120 or 240V DC) or much bigger wires (for lower voltage) and modifying your devices to work on low voltage.

Wire length. For low voltages, the voltage drop is important, which means that a longer cable needs to be thicker. If you replaced the 2 meter long cable from the wallwart to your TV with a 20m cable you would have to have a much bigger cable. RVs are small, so the cables in them are short, letting you get away with low voltage.

Actually it would be worse. For 220V AC the wiring is usually sized so it does not melt under full load (full load results in a specified temperature increase), which means that you can use the same size wire for a 1m or a 20m required.length. For low voltage (12V and especially 5V) the wire would have to be much bigger than the "don't melt" requirement since now the voltage drop would be more important. Also, a 20m wire would need to be thicker than a 1m wire.

Low voltage distribution won't work, even just inside the home for high power devices.

Low voltage both needs a bigger wire due to higher current and at the same time is more sensitive to voltage drop (5V drop for a 12V line is much worse than 5V drop for a 220V line). So, plugging in a computer (300-500W more if it's a gaming rig with four video cards) or a big TV (150W) or AC (1kW or more) or electric kettle (2kW) or something else that uses a lot of power is not practical with 12V.

OK, so let's up the voltage to 48V. Now the TV needs 3A, a PC needs 10A and the kettle needs 42A with permissible voltage drop of 4.8V. This can be doable (except the kettle), but you still need big wires and outlets. Also, you still need DC-DC converters for most devices as they do not run on 48V internally.

As for having three different voltages (12, 48, 220 AC), that would be really inconvenient. Do you want to be able to plug in you vacuum or kettle in every room? Well, every room has to have a 220V outlet. And those are where the highest power devices will be plugged in. OK, your phone can charge on 12V. Do you want to run a separate cable just for the phone? How much power will it save? When the cost of running the wire will pay off in the conversion savings?

As for battery backing the low voltage and not backing the 220V - well, if my heat pump, AC, furnace and servers are connected to it, while my phone charger is connected to 12V, guess which line I will want to have backup power?

Also, backward compatibility. If my radio can only work on AC, then I am going to need a 220V outlet for the radio.

Would it not be possible to repair the genes? If DNA gets messed up, why not keep a backup with multiple copies and (important) checksums to refresh the copies stored in the cells once in a while so it does not become too corrupt? The DNA is a few gigabytes IIRC, easily stored in a small chip.

Now, currently I do not know of a way to actually repair the DNA in cells, but maybe at some time in the future some smart people figure this out...

Yea, there are exceptions, but the "norm" is that girls are not into technology. I am not saying the "norm" is good, but it is what it is.

Also, women are diffrent from men in physical strength. Sure, there are a lot of women who could beat me up or lift more weight than I can, but if you chose a man and a woman at random there is over 50% chance that the man would be stronger than the woman. I do not know if this also applies to the ability to program.

In my opinion the current system, while not perfect, is still better than privately owned police (who would only do stuff for money, therefor, only for people who have (lots of) money).

Companies shouldshould try to pay as little as possible. That's the system: it depends on human greed at every exchange. Any system that doesn't is purest foolishness.

Sure, however, while Free Market looks good in theory, so does Communism. The problem with both is that they are not achievable in reality, we can only have weird mangled versions of them.

Let's have private companies in charge of everything! That will work great - they will not try to make more profit than they have to and if they still do, we can vote them out in the next election.

So, I am sure that I won't have to pay $100000 in case of a fire, $20000 to have the police find the guy who beat me up (and another $20000 to have the court send him to jail) and $1M to repair a road.
