Comment Re:Electric jet? (Score 1) 163

You don't have to burn fuel to have a jet - you just need something to spin a compressor. Gas turbines just happen to be an easy way to do this with impressive power to weight and power to volume density. I know there is lots of research into electric compressors, but I didn't realize they were getting that competitive; I've been out of that industry for a while.

I say we forget trying to sequester carbon. Instead, we should create artificial hurricanes. This will have two effects: more transfer of heat from the surface to the upper atmosphere where it can be radiated to space, and since hurricanes are massive heat engines, we can just use them as power plants.

Win-win!

I'm only half-joking.

Comment Re:Barrier of entry? (Score 1) 149

'Safe' vs 'unsafe' I think is the wrong dichotomy.

Consider that the world actually needs 'unsafe' tools - for instance: knives, saws, fire. But what you want in tools like this is they always act in a nice deterministic way so, if you treat them with respect, you can obtain useful work from them.

Code is essentially the same thing. What is necessary is the proper amount of respect for the damage your tools can inflict, not suggesting everyone to use safety scissors (except where it's appropriate of course).

Comment Re:Scary stuff (Score 2) 279

I think the bigger issue is that some people can sacrifice basically their entire standard of living and it still won't guarantee a particular outcome. And this isn't even on the backs of the "wealthy fossil fuel barons" - this is just the average everyday person.

So it boils down to "absolutely everyone must do something" and the backlash of "who are you to tell me what I should do."

So then you get into "since everyone isn't doing it, I'm not going to sacrifice..." and nothing happens. Basically you have to accept forced behaviors or penalties - which a substantial portion of the population (not just in the US, by the way) takes issue with.

Comment Re:Globalisation (Score 1) 392

The short response is, of course, "it depends."

There are essentially only two types of economic activity: creation of wealth and trade. Creation of wealth is actual manufacturing or agriculture that generates consumables or what I would call "productive infrastructure" like machines or homes or storage facilities. Trade - while it may indeed generate value for both parties involved in the trade, cannot generate wealth.

In the general economy is a combination of activities where some people / organizations do actually invest in new production to create wealth so in aggregate it is true that the economy is not "zero sum". But at some point things bifurcate: a portion of the population is no longer able (for some reason or another) to generate new wealth, but instead can only trade.

For the portion of the population that can only trade, it is indeed a zero-sum game, except for the instances where the actual wealth producers inject new wealth into the trade markets.

So yeah, a Gates or Buffet or whatever doesn't necessarily prevent new wealth from being created - but as wealth concentrates, there isn't necessarily any impetus for the wealthy to generate more wealth (in fact, diminishing marginal returns say at some point it won't). We are just assuming that the wealthy will continue to want more - but at some point, they are effectively self-contained and would no longer have any need for trade. At that point - what happens? This is the source of fear (rational or not) from globalization and automation - when the owners of productive capital no longer have a need or desire to trade with non-owners.

To summarize - and I do agree it is theoretical/hypothetical: super-wealthy entities harm non-wealthy when, instead of using that wealth to increase production (through productivity increases or just new capacity at the same productivity levels), that wealth is only used to acquire ownership of a larger portion of the total available wealth (e.g., rent-seeking).

Comment Re:VAT is the answer (Score 2) 392

A VAT is actually counterproductive - you don't want to tax adding value!

What we really just need is an ownership tax - perhaps something like a property tax. The simplest form is this: your income tax rate is proportional to your ownership percentile.

This means if you own a lot, but have zero income, you get low tax - so you can keep your wealth. If you own nothing, and suddenly get income - you get to keep most of your income.

If you have massive wealth and massive income, you get taxed massively.

This solves most of the adverse incentive problems in any other form of taxation, but it has to be accepted that its unabashed purpose is to dampen wealth concentration effects.

Comment Re:Globalisation (Score 1) 392

If someone (or small enough group) has so much of the wealth that it's no longer possible for anyone else to obtain means of production, that's the problem.

Put another way - poverty is a result of being unable to produce something you need yourself or being unable to trade what you can produce for something you need. The reasons for that can be many, but the result is the same: if you can't produce what you need or get it by trade (or by gift), you're poor.

If all the wealth - that is, means of production and tradable goods - is owned by a small group, and you can't even provide a service for which those owners are interested in trading, and the government doesn't "tax" that wealth to redistribute it to you, you're SOL.

Comment Re:Always wait for the S version (Score 1) 114

Funny thing with this rationale is that it fails to quantify the benefit of not having a monthly payment obligation.

Also - if you have $800 in your pocket now and you want to take out a 0%/24-month loan and "invest" the cash instead of buying outright, that means you have to have an investment where you can withdraw $33 a month to make the payment on the 0% loan. You can't just pay that $800, say, into your mortgage because that money is not really liquid and you can't use it to make the payments on that 0% loan.

Comment Re:Atl-math (Score 1) 229

Just for reference the important caveat is no logic that can encode basic Peano arithmetic can be consistent and complete. There are plenty of axiomatic systems that are complete and consistent, even complicated mathematical ones (the first order theory of complete ordered fields, a.k.a. the real numbers is complete and consistent). Also a stronger logic can prove the consistency of a subset contained within it. Thus the first order theory of Peano arithmetic can be proved to be consistent via second order logic. Finally you may also want to look up Tarski's indefinitability of truth -- a theorem which gives the results you have here as a corollary, but is simpler: in sufficiently power logical systems you can't even define a truth predicate.

You are simply mis-reading what is stated in that document. The US citizen parent had to be resident in the US for ten years (prior to the birth). How can I be so certain? I am in a similar category, but was born outside the US to a US mother and a father who had not been ten years resident in the US. I had, since birth, US citizenship until I renounced a few years ago.

Comment Re:APPLICATION, not PATENT (Score 1) 62

I'm pessimistic and think, sadly, that you have too much faith in the patent office.

The correct response to this doesn't even have anything to do with "an abstract idea" - it should be "You have a device that is designed to take pictures and can identify objects in those photos, and that device has location information and storage. Using that device to keep track of the locations of objects is obvious - not patentable.

The only thing patentable would be if they had some novel way of storing location information perhaps, or some novel method of object recognition. The "idea" "keep track of objects' locations with a hololens" should not be patentable at all.
