Comment Re:Common sense space exploration (Score 1) 83

Adding to my comment above: a generation ship consisting of six individuals supervising embryos in perpetuity ignores the entropy associated with human psychology. A certain percentage of the population are psychopaths. What happens when one of the six decides a few generations down the line decides to murder the other 5? Perhaps that can be avoided with careful genetic engineering, but even that ignores the foibles of human psychology. Is it really realistic to expect someone to live with 5 other humans for an entire lifetime cooped up in a tin can with no hope for an escape from the monotony of maintaining the ship? All it takes is for one generation to fail to fulfill their duties and the ship is toast. You could have the ship all robotized and only embryos, but it's unclear whether it's possible to rear a healthy adult from a child who has never had adult human contact.

Even a generation ship like you describe poses technical problems that may very well be insurmountable.

One issue is small particles in space (micrometeorites). While the space station may have managed to avoid catastrophic impacts over a decade, the probability of a major impact on a ship traveling for centuries at even a very small fraction of the speed of light hitting *something* in space becomes extremely high. At those speeds, a golf ball size object would slice through any known material like a hot knife through butter and could easily breach every single pressurized chamber on the ship. You would need some sort of powered force field- a technology that does not exist and has no known theoretical basis for its existence.

Another issue is food and biology. Previous attempts and creating a small closed ecosystem (biosphere) were miserable failures. It may very well be that there is a minimum size for such an ecosystem to be sustainable- a size that may not be feasible for a spacecraft.

A third issue is propulsion and power. The generation ship proposes relatively slow travel as a solution to the tyranny of the rocket equation. But even the generation ship must provide power for centuries. Even using nuclear fuel, the amount of fuel required to power the spacecraft essentially indefinitely would become extreme. Plus, getting the spacecraft up to even a very low cruising speed (by interstellar standards) of .01c would require a huge amount of any known type of fuel, and an equal amount of fuel to slow to a speed that it could orbit the new planet. What happens if it turns out the destination planet is not actually habitable? There would be no fuel left to choose an alternate destination. At that point, the generation ship offers no advantage over a colony on the moon.

A final concern is one of need. Interstellar travel proponents often use the argument that the Earth may one day become too small to support the human population and/or uninhabitable, requiring a new planet. But until the sun starts to begin its decay in billions of years, it's difficult to imagine a scenario where interstellar travel is more feasible than simply fixing earth. Human population size will likely decline as birth control becomes ubiquitous (the developed world already has a birthrate below replacement). Any civilization with the technology to create a closed ecosystem with an indefinite lifespan for a generation ship could just as easily create such an ecosystem on earth or bio engineer a solution to what ever disaster has befallen earth.

Before we can "invest in technology" we need to have some theoretical basis for said technology to work. Our current understanding of physics provides no plausible mechanism for a living human to travel to these planets. Unless there is a fatal flaw in relativity, it is possible (if not probable) that practical interstellar travel is essentially impossible.

Comment Re:It won't stop at 85 (Score 1) 525

It's been my observation that there is a limit to speeds people are comfortable at. The speed limit on Highway 287 in Texas (Dallas to Amarillo) used to be 65mph. People would usually drive around 75mph and there were speed traps everywhere. Recently, the limit was raised to 75mph. People still mostly drive 75, but the speed traps have thinned out considerably. Road noise and wind buffeting mean that most (non sports) cars start to feel a little squirrely above 80mph. Above 90, most economy cars will be struggling just to sustain speed with the pedal floored.

I find a lot of people who claim to have "tried" diet an exercise haven't effectively done either. "Exercise" does not mean sitting on a recumbant bike for 30 minutes while reading a magazine a few times a week. Sure, it's better than nothing, but it's not going to burn significant calories or increase your basal metabolic rate much. Likewise, "diet" does not mean switching to the "low fat" or "diet" versions of the foods you usually eat.

Effective exercise involves BOTH cardio and strength training. Cardio 5x a week, strength 3x. Unless you have a diagnosed health condition other than weight, it should not be moderate- It should be vigorous. Cardio can be pretty much anything, but it should involve periods above 80% max heart rate. Endurance exercise (1hr+ exertion) at a lower heart rate should be mixed in as well. Proper strength training involves doing sets of major exercises (deadlifts, squats, bench press, rows) until or near failure. Things like dumbell curls and kettlebell swings are fine supplements, but you won't see much in the way of gains from doing endless reps of curls on a 5lb dumbell.

Effective diet involves eating whole unprocessed foods with a lot of micronutrients. Don't drink your calories (most caloric drinks get that way through sugar). While the exact components of an ideal diet are a matter of debate, it's pretty clear than anything that comes in a box or can or sealed bag is a lot less likely to be healthy.

If you do the above, you will burn significant calories from the cardio and significantly increase your basal metabolic rate by adding muscle. Your total calories will likely decrease without any conscious reduction efforts because fresh fruits and veggies will fill you up a lot faster than a bag of Doritos. None of this is rocket science, but sadly is ignored by most people looking to loose weight. Mostly because it involves a lot of hard work (it will take a year of consistent training for your strength efforts to be visible), and because there is no gimmicky product to sell. All you need is the produce aisle, a good barbell set/bench/power rack, and a pair of running shoes.

Re Lawyer compensation:

It's true that a partner at a large firm can make $500k (indeed, some make millions per year), but that's a tiny fraction of lawyers and they do work close to every waking hour. This is at most 1-2% of practicing lawyers. Very successful plaintiff's lawyers can make millions on one case, but have no steady income. Of highly paid lawyers, much more common are large firm associates (start at $160k and go to $280k or so), or in-house lawyers at large companies ($110-$300k depending on seniority). The in-house lawyers often get pretty close to 9-5 hours. That said, at least 50% of lawyers are fighting for table scraps and make much less. It's true that nobody does lawyer work as a hobby (you need a client, so you can't just do it for no reason), but plenty of lawyers do free legal work for the poor.

The bottom line is all highly paid jobs require significant expertise and the very top of most professions make very outsized salaries compared to the average practitioner.

You are quite simply wrong. An attempt at a monopoly is illegal too. You don't have to have one. See section 2 of the Sherman antitrust act. No, shutting down the CurrentC app wouldn't be a slam dunk antitrust case, but it would absolutely carry antitrust risk- especially if Apple colluded with Google. IAAL.

The antitrust laws are a bit more complicated than that. You don't need to have an actual monopoly to violate them (likewise, a monopoly alone is not illegal). Microsoft didn't have a monopoly on computer operating systems when it was attacked for antitrust law violations. Shutting down the currentC app would be anti-competitive behavior, which is always risky from an antitrust standpoint for a player with a dominant market position.

Well, yes and no. A truly small business started by a single individual (or spouses) will be treated as a disregarded entity unless it elects otherwise or forms a corporation, which does not subject the business person to the full brunt of business tax complexity. It's more complex to run a small business, but mostly from an administrative standpoint (i.e. keeping all your receipts, etc.). The actual tax law that applies to such small businesses wouldn't expand all that much. But, in my experience, the people who really get into trouble with the IRS tend to be small business people. Big businesses have the technical and administrative resources to follow the law.

A VC funded startup will have tax planners on the VC side.

I'm not ranting about average people at all. Just clarifying. Actually, the tax code for most individuals doesn't need to be all that complex. The U.S. could do what the UK does and have a pro forma tax return for W-2 wage earners and eliminate the need for 90% of the population to bother filing a return. However, that would require tax reform which has proven to be a near impossibility. You could simplify business taxation to a large degree with some key reforms, but as long as you make "Income" the tax base, you are going to have a complex tax code for large business enterprise. However, the large business enterprises aren't getting away with murder to the degree that most people suspect. Remember, corporations are just vectors. Ultimately a real human being has to pay tax, so corporate tax complexity can be a bit of a red herring.

As for the necessity of my profession... any time you have laws, you need someone who specializes in their interpretation or application. Name me a type of law, and I will name you a specialized practitioner. Doesn't matter whether the law itself is simple or complex.
