I suppose I disagree with the formulation of the argument. The entscheidungsproblem and the halting problem are limitations on formal analysis. It isn’t relevant to talk about either of them in terms of “solving them,” that’s why we use the term undecidable. The halting problem asks, in modern terms—
Given a computer program and a set of inputs to it, can you write a second computer program that decides whether the input program halts (i.e., finishes running)?
The answer to that question is no. In limited terms, this tells you something fundamental about the capabilities of Turing machines and lambda calculus; in general terms, this tells you something deeply important about formal analysis. This all started with the question—
Can you create a formal process for deciding whether a proposition, given an axiomatic system in first-order logic, is always true?
The answer to this question is also no. Digital computers were devised as a means of specifying a formal process for solving logic problems, so the undecidability of the entscheidungsproblem was proven through the undecidability of the halting problem. This is why there are still open logic problems despite the invention of digital computers, and despite how many flops a modern supercomputer can pull off.
We don’t use formal process for most of the things we do. And when we do try to use formal process for ourselves, it turns into a nightmare called civil and criminal law. The inadequacies of those formal processes are why we have a massive judicial system, and why the whole thing has devolved into a circus. Importantly, the inherent informality of law in practice is why we have so many lawyers, and why they can get away with charging so much.
As for whether it’s necessary to be able to write a computer program that can effectively analyze computer programs, to be able to write a computer program that can effectively write computer programs, consider… Even the loosey goosey horseshit called “deep learning” is based on error functions. If you can’t compute how far away you are from your target, then you’ve got nothing.
This is proof of one thing: that our brains are nothing like digital computers as laid out by Turing and Church.
What I mean about compilers is, compiler optimizations are only valid if a particular bit of code rewriting does exactly the same thing under all conditions as what the human wrote. This is chiefly only possible if the code in question doesn’t include any branches (if, loops, function calls). A section of code with no branches is called a basic block. Rust is special because it harshly constrains the kinds of programs you can write: another consequence of the halting problem is that, in general, you can’t track pointer aliasing outside a basic block, but the Rust program constraints do make this possible. It just foists the intellectual load onto the programmer. This is also why Rust is far and away my favorite language; I respect the boldness of this play, and the benefits far outweigh the drawbacks.
To me, general AI means a computer program having at least the same capabilities as a human. You can go further down this rabbit hole and read about the question that spawned the halting problem, called the entscheidungsproblem (decision problem) to see that AI is actually more impossible than I let on.
Computer numerical simulation is a different kind of shell game from AI. The only reason it’s done is because most differential equations aren’t solvable in the ordinary sense, so instead they’re discretized and approximated. Zeno’s paradox for the modern world. Since the discretization doesn’t work out, they’re then hacked to make the results look right. This is also why they always want more flops, because they believe that, if you just discretize finely enough, you’ll eventually reach infinity (or infinitesimal).
This also should not fill you with hope for general AI.
Evidence, not really, but that’s kind of meaningless here since we’re talking theory of computation. It’s a direct consequence of the undecidability of the halting problem. Mathematical analysis of loops cannot be done because loops, in general, don’t take on any particular value; if they did, then the halting problem would be decidable. Given that writing a computer program requires an exact specification, which cannot be provided for the general analysis of computer programs, general AI trips and falls at the very first hurdle: being able to write other computer programs. Which should be a simple task, compared to the other things people expect of it.
Yes there’s more complexity here, what about compiler optimization or Rust’s borrow checker? which I don’t care to get into at the moment; suffice it to say, those only operate on certain special conditions. To posit general AI, you need to think bigger than basic block instruction reordering.
This stuff should all be obvious, but here we are.
The thing that amazes me the most about AI Discourse is, we all learned in Theory of Computation that general AI is impossible. My best guess is that people with a CS degree who believe in AI slept through all their classes.
The issue will have to be litigated, but… A lawyer once told me that there aren’t really “lawsuits” so much as “factsuits.” The actual judgment in a trial comes more down to the facts at issue than the laws at issue. This sure looks an awful lot like IBM strong arming people into not exercising their rights under the license agreement that IBM chose to distribute under. If it is ever litigated, it isn’t hard to imagine the judgment going against IBM.
I sometimes get mistaken for the human pope, while you can clearly see that I’m the raccoon pope.
While there are technical solutions to that problem, realistically it’s only a problem if people start thinking they’re celebrities. Personally I prefer a platform that lets people dunk on celebrities.
So uh… who put the house up for sale? Did the bank foreclose on the house?
Fun question, but it leads to other questions…
First, are vampires stopped at the property line, or only at the threshold of some appurtenance (e.g., a house)? After all, you’re asking about real estate, and real estate is primarily concerned with land, not buildings.
This sort of matters because, are we assuming that vampire law is coincident with human law? By this I mean, if vampires were to take control of the government and abolish real estate law, would they then be able to enter any property or building, anywhere, anytime?
If vampires do observe human law, then realistically, they probably wouldn’t be able to enter a leasehold without the tenant’s permission. The fundamental right of tenancy is peaceful enjoyment, and in fact tenancy is a legal property right, to access the property in question and do anything, without undue burden, allowed under the terms of the lease. It would be a violation of peaceful enjoyment for a landlord to allow vampires into the unit.
The right of inspection, by the way, is explicitly carved out in real estate law. The right to let vampires into the unit is, to my knowledge, not enumerated.
I got a 19/20, and it reports the one missing point as being slightly skeptical. I’m guessing it was this headline, which I marked as fake: “International Relations Experts and US Public Agree: America Is Less Respected Globally.”
I feel like this is actually a test of two things: first, can you recognize the form that headlines tend to take? and second, can you recognize the kinds of things the media would be willing to say? The reason I marked that headline as fake is because it sounds slightly more casual than I’d expect.
So it’s no surprise that boomers would be able to answer those particular questions with more accuracy, because they grew up with headlines looking like the “real” headlines in the survey. Or put very bluntly, this is primarily a survey of how in-touch you are with boomers’ mode of journalism.
Boomers score highest on this test.
Stop the presses.
The other issue to consider is MBAs. Or at least the MBA way of thinking, that “caring about customers” actually means “leaving money on the table.” The relentless search for “business efficiency,” evaluated in pure accounting terms, can easily lead to destroying the core business due to a lack of understanding of how the core business shows up on a P&L statement.
Glow-in-the-dark heating elements…
Seatbelts don’t eliminate the possibility of dying in a car crash, but you should still wear one.
It’s a staggering display of stupidity that some people think vaccines must completely eliminate risk, or else they’re useless. The unredacted portion is just about how some people do get symptomatic COVID despite being vaccinated. Never mind that their symptoms are, on average, much milder than those of unvaccinated people, or that their chances of getting “long COVID” are much lower.
This is, in any case, the perspective of someone who’s never had to take any responsibility for any single thing in their entire life.
As I recall, the basic differences between employee and contractor are whether the employer can dictate time, place, and manner. The problem for gig “contractors” is that they’re in a much tougher spot on exercising their rights, since not many people who can afford a lawyer deliver food. And they aren’t exactly in short supply, so if Uber oversteps and individual “contractors” try to push back, they’ll just be fired. Which gets back to the lawyer issue.
