It's physics, it's hard to dump 80MWs of heat in space and wishing won't change that. Invent a better way to extract electricity from nuclear fuel, perfect fusion, or use solar panels seem to be the current choices. It would be nice to have some breakthroughs, especially a reaction less drive that uses little power.

The questions were already looked into back in the '60's, the math is pretty basic. Basically for a reactor in space, you need a heat dump and all that works in space is a radiator. I don't know the math but I'm pretty sure a radiator that can dump 80 MWs of heat would be very big. Same with a centrifuge, though there you can take shortcuts such as having 2 capsules connected by cable spinning around a central point or better connected to a central object such as a booster.
It's engineering on a very large scale, in space. $23 Billion would be a start just like the ISS is a start on learning how to build stuff in space, which turns out to be quite hard.
Just like the first ship building started out by building small boats and then scaling them up while doing lots of learning, space ships will be the same. Be nice to learn more about reactors in space (along with on the Moon and Mars) but we'll have to start small and then scale up.

1. A very powerful and long lasting power source. Think naval reactors or other self contained, compact reactors. We are talking 80 megawatts of power or more. The more the better.

Besides what the AC said about mass, you're talking about a 80 MW steam engine in space, you need water and you need a huge heat sink for a nuclear reactor, which is actually just a steam engine.

4. "Artificial" gravity. Actually, a huge centrifuge for the living/working quarters.

You might be unpleasantly surprised at how big a centrifuge has to be to generate a decent amount of centripetal force close to equally over the average persons 6 feet as well as to keep the sideways forces to a minimum.

5. Lastly...engines. Banks of ion engines, the infamous and yet to be proven EM drive, or who knows what else.

See number 1, how the hell are you going to power it as steam engines don't work that well in space.

No, the goal of copyright, at least in the English speaking part of the world, was, to quote the long title of the first modern copyright act,

An Act for the Encouragement of Learning, by Vesting the Copies of Printed Books in the Authors or Purchasers of such Copies, during the Times therein mentioned.

This is also reflected in the American Constitution, where the Arts & Sciences at the time meant education.
The lengths of copyright was also much shorter, but long enough for creators to recoup their time.
Meanwhile, right from the beginning, the Stationers or Publishers, were pushing for infinite copyright, claiming it was for the artists that they paid a pittance to for rights. They fought in the courts when the first copyrights ended and the courts ruled that copyright is not a common law right, so they bribed the legislatures to steal from the public domain.
Most all that massive amount of copyrighted material that you mention is supposed to be in the public domain to advance learning and 14-28 years is plenty enough time for the artists and publishers to make their money.

Again, not relevant since CO2 is not pollution and the argument against CO2 is a totally different one than against real pollution. Nature loves and uses CO2 (do you even know how plants live???)

Do you feel the same way about shit, I mean fertilizer? Nature loves and uses shit (do you even know how plants live???)
Probably was repeated back when the germ theory of disease was advanced and scientists wanted to spend money on wells far away from the cesspools. Surprised people still aren't bitching that the germ theory is not settled science as science always means being skeptical and not spending money on stupid stuff like keeping drinking water separate from healthy plant fertilizer.

To quote someone on mozilla.dev.apps.seamonkey

Practically old extensions are already obliterated piecemeal by changes in Gecko. Older javascript language constructs get removed and old apis too. With 2.49 and then again with 2.50 a lot of them will break.

As far as i see it web extensions don't cut it yet and probably never will. They are also still a moving target and even gecko is slowly becoming a construction site with Servo and Quantum.

But SeaMonkey has imho not enough developers to retain the stuff. Porting web extensions need to be done in the future and even this will not be easy.

I would say enjoy it while it lasts and we will see what comes of it.

I've seen quite a few similar postings. Basically SeaMonkey (and Thunderbird) just don't have enough developers to do a lot of stuff including getting out regular releases, little well forking Gecko.

While people living in poverty have it easier then the States, there's still a certain amount of prejudice in the system. Poor people are less likely to have a family doctor, so reduced to hanging out at clinics to be seen by a Doctor who is likely to treat them worse as they're poor. Pharmaceuticals, while cheap by American standards, are expensive by first world standards and not likely to be covered by pharmacare etc unless person is disabled. The government doesn't cover things like dentists, optometrists so the poor are likely to have bad teeth and old glasses.
On the other hand, middle class people are likely to have more covered in their benefits from work and the rich pay the same $70 a month as the person making $50k. Here in BC, $50k is basically poverty wage due to the expense of housing.
There is a lot of variety between the Provinces as they're in charge of medical with the Federal government setting minimum standards and I've only experienced healthcare in BC.

The other question is "how does the *AA feel about libraries". My wife borrows a dozen or so DVDs every week or so, which doesn't seem much different then piracy. Library buys one copy and it gets shared, heavily in the case of new releases. I have the feeling that libraries wouldn't exist if the *AA had their way and we're lucky that they didn't have any power a hundred years ago.
Publishers and the parent posters brother probably hate me for borrowing books as well.

Well if you think that the BC Liberal Party is left of center, it really makes me wonder what you consider right wing. To quote from the BC Liberals web site, https://www.bcliberals.com/

Who We Are

As BC Liberals, we’re proud of our diversity – and united by the free enterprise values shared by the majority of British Columbians. We’re focused on making BC even stronger, more prosperous, and more sustainable.

which given the traditional left, for the workers or regular people, right for the factory owners or rich, seems weird. The problem is that it is very hard to simplify things down to a 2 dimensional line when it comes to politics or actually human nature.

So basically the future is one where the banks and telecommunication companies skim all our money.
I'm in Canada, the banks are expensive to deal with, as much of their income comes from user fees that are forever increasing. They also don't like giving out accounts to the poor.
The telecoms are horribly expensive, especially for data, from $1 for 20MBs a day to $30 a GB (text messages are $0.15) are the prices that I see for a pay as you go costumer, and not much better with monthly billing. Similar to the banks, the cell companies raise their prices regularly and in lockstep.
Then there is the matter of reception, fine if you live in town but I'm 70 kms out of the 3rd largest city in Canada and don't have reception. Most of Canada is much more rural.
America isn't much different, cheaper cell, lots of rural areas, banks that don't like dealing with poor people and a population that won't even give up their penny that has no buying power.
