  1. Is this going to be so desirable in a datacentre of all places where power consumption and cooling are already a significant portion of a system's ownership costs?

    The answer is yes.

    Because the critical considerations are compute efficiency (wallop per watt) and compute density.

    Escalating wallop density is ultimately going to cost you on the TDP front, except as compared to free lunch.

    A = 2 x (1 platform + 1 CPU)
    B = 1 x (1 platform + 1 turbo CPU)

    Suppose turbo CPU is 50% hotter, 100% more powerful.

    Or perhaps you've swallowed the SOC blue pill in a single gulp, and think that the mainboard is just a bunch of fiberglass, epoxy, plastic restraining clips, and copper artwork.

    The mighty 6" between your two CPU sockets doesn't come for free, either. (Also known as mighty slow, as in ye mighty 6" of the 1 ns electrical round tip.)

    You seem to suffer from a complete and utter inability to navigate counterfactual statements.

    Counterfactual Discourse in Context — January 2017

    The classic Lewis-Stalnaker semantics for counterfactuals captures that Sobel sequences are consistent sequences, for example:

    • If Sophie had gone to the parade, she would have seen Pedro dance.
    • But if Sophie had gone to the parade and been stuck behind someone tall, she would not have seen Pedro dance.

    But reverse a sequence like this one and it no longer sounds so good, which is surprising on the classic semantics.

    This observation motivated Kai von Fintel (2001) and Thony Gillies (2007) to propose dynamic semantic accounts of counterfactual conditionals.

    Subsequently, Sarah Moss (2012) defended the classic semantics against the charge that it need be abandoned in the face of these order effects, arguing that the infelicity of the reverse sequences is pragmatic.

    I argue that both accounts are ultimately untenable, but each account has strengths. Seeing what works and what doesn't in each account points the way to the right positive view.

    With this in mind, I defend a contextualist account of counterfactuals that takes conversational relevance to play a central role.

    What a person "would have preferred" tends to scamper down this rabbit hole in a big hurry.

    Jump, jump, you should follow.

    Simultaneous Interpreting: Some Frequently Asked Questions!

    Simultaneous interpreters normally work in teams of two per booth, taking turns in shifts of about 30 minutes each for a maximum of about three hours at a time, which has been found to be the maximum average time during which the necessary concentration and accuracy can be sustained.

    For some reason, this came up in a machine learning resource I consumed recently.

    Of course, this job is likely to be impacted fairly significantly, if the computers ever get to the really high level of accuracy required to pass the SALT hurdle.

    Sub-second trading granularity just isn't adding anything meaningful, but it causes crazy distorted and unfair trading practices. Something like shuffling transactions over a larger timescale that is more fair.

    It's extremely hard to create a batch clearance protocol (say, once per minute) where you don't create an information hazard where firm A arranges to receive a vital public stock press release a 0.1 ms before the cutoff time, while it's competitor receives the same press release 0.1 ms after the cutoff time. You just have to pick the right city to post the first formal announcement.

    Trust me, with this kind of trading advantage available, Bitcoin would flow into the dark wallets of press release enter-key jockeys everywhere.

    Okay, you have a better idea. So you create a worldwide publication system that makes the same information available to everyone 10 s before the trade block, after which even Twitter falls silent. Now everyone bidding is on a level information playing field. (Hey there, Mr Greedy Stockbroker, no talking out of school using spread spectrum!) Maybe you settle a global trade auction once per hour, prior to which all new information on the planet that makes the cut is bundled up into some kind of giant ZFS Merkel tree, and everyone gets a copy. Then, for 10 s before the hour, all global fiber and radio goes dark until everyone places their fair bids, to be resolved by the One True Settlement Pass.

    Sound like a plan?

    HFT truly is a pox on humanity, but unfortunately, the pox has a billion year precedent: organisms have always competed for having the fastest nervous systems, and figuring out a way to gain proximity on the vital and timely survival information.

    At the end of the day, HFT is just biology pursued by other means.

    But with some peculiar twists.

    Imagine how—in this New World Order—the Pompeii office places some extremely shrewd bets in the microseconds before it ceases to exist.

    I've so far only managed to come up with one proper solution: build a Ringworld. A Ringworld where all news is effectively local news (so long as walls perform). A Fukushima incident takes out the entire conflict metal supply in Scorpio quadrant? Surely the localized market blip is hard to detect a mere 5 light-seconds upring or downring.

    Some of the most interesting features of the Ringworld economy are dictated less by its size, than it's fundamentally linear macro-scale geometry.

    Now, there would still be some competition to create the fastest possible communication network, Ringworld-wide ("wide" on Ringworld generally means "trivial in size", but we'll ignore this). The fastest diametric system probably involves shooting polarized neutrinos straight through the sun. If macro-HFT nanoseconds matter enough to you, surely you'll figure this out.

    * Talking Machines: Remembering David MacKay with Philipp Hennig — 21 April 2016

    * Probabilistic-Numerics.org

    This is plain old numerical methods, optimization, and search viewed through a Bayesian inference filter. I would never have termed any of this "artificial intelligence".

    It took the recent large advances in unsupervised learning, the kitty classifier (and progeny), and the LSTM machine translation models to finally justify rethinking academic labels. Programs like SHRDLU from 1968 were perhaps explorations in AI, if our baby-step microscope is especially well focused. But this was closer to natural philosophy than what later became physics. Even our shiny new LSTM language models remain weirdly proximal to Searle's Chinese room. What have we really learned from watching our machines learn? Not a whole damn lot.

    An Alberta AlphaGo Pioneer Is in China to Watch the AI Wallop Human Opponents

    "Before AlphaGo, much of the fundamental games and machine learning research was done here," Muller wrote in an email. "If you look through the references list of the AlphaGo paper in the journal Nature, over 40% of these references have a University of Alberta (co-)author. Then, DeepMind greatly surpassed all of these previous efforts with their new ideas."

    I haven't waded through this yet, but I suspect even the vaunted AlphaGo has a backbone of techniques that I personally wouldn't have classed as "AI" (or even AI-ish) by my own standards.

    For decades, the big idea in AI was supposed to be recursion. Perhaps human language is recursive in theory, but it's only barely recursive in practice (nest more than three levels, your accurately attentive audience grows thin). Winograd is not completely wrong about this, but my long suspicion is that recursion is not going to enter the AI building through the ground floor.

    Lately, we really have hit home runs with distributed representation, and to a lesser degree with convolutional image recognition. These are actual AI-ish ideas. However, two solid take-home techniques do not a field make.

    Here's another possible intermediate term: generalized gradient exploitation (GGE). Plus there's tons of great mathematics about overfitting and regularization. But should we really call all this math "AI"?

    In practice what AI ends up meaning is "look ma, no code!" Hey, we just built an impressive system without hiring rooms full of code monkeys, so we must be doing something right.
