That sounds not entirely ethical / honest..
Or can anyone recommend something lighter-weight than full-blown Kafka etc.?
Not only does nanosecond resolution provide zero benefit, models indicate that it actually harms liquidity. To be specific, serial order processing in continuous-time is more efficient in "time-space", but less efficient in "volume-space". The better mechanism is batch order processing in discrete-time (i.e. process all arriving orders simultaneously in batch every 100 milliseconds, rather than one-by-one every nanosecond): http://faculty.chicagobooth.edu/eric.budish/research/HFT-Fre...
> Dr. José Luis Torero, an internationally recognized fire-investigation expert, was hired by the GIEI to conduct an independent examination into the incineration scenario. Torero, a Peruvian who participated in the forensic investigations of the World Trade Center attacks, has a Ph.D. from the University of California, Berkeley, and was previously a professor of fire security at the University of Edinburgh. He currently heads the School of Civil Engineering at the University of Queensland, Australia. The incineration of forty-three bodies in an open-air terrain like that of the Cocula dump, Torero concluded, would have required some thirty-three tons of wood or fourteen tons of pneumatic tires, along with the same amount of diesel fuel; the fire would have had to burn for sixty hours, not the twelve that the P.G.R. claimed it had, based on the confessions of captured Guerreros Unidos sicarios. The smoke from such a fire would have risen nearly a thousand feet into the sky and would have been visible for miles around; no such pillar of smoke was spotted, or even captured by satellite imagery.
The pro-government media is pushing back that its just one scientist's opinion, which is at odds with the opinion of scientists at UNAM (national university of mexico) who participated in the government investigation and concluded that the missing students _were_ incinerated.
> Suppose that earthquakes and burglars can both set off burglar alarms. If the burglar alarm in your house goes off, it might be because of an actual burglar, but it might also be because a minor earthquake rocked your house and triggered a few sensors. Early investigators in Artificial Intelligence, who were trying to represent all high-level events using primitive tokens in a first-order logic (for reasons of historical stupidity we won't go into) were stymied by the following apparent paradox: [.. snip ..] Which represents a logical contradiction, and for a while there were attempts to develop "non-monotonic logics" so that you could retract conclusions given additional data.

The article does mention p2p and decentralization, but the browser isn't whats holding that back. The client-server development paradigm is.
Currently, every dev making a p2p app has to roll their own platform because there's no standard (i.e. no LAMP, rails, or Heroku for deploying p2p apps). Some projects are working to change this, namely BitTorrent Maelstrom (which is a fork of Chromium with native support for magnet URLs, so it auto-renders an html/js package distributed via torrent); and http://ipfs.io (a sort of content-addressable p2p filesystem, or bittorrent on steroids).
Also, the reason package managers suck is because.. entropy. See Joe Armstrong, The Mess We're In http://www.youtube.com/watch?v=lKXe3HUG2l4
That's not the thing we should be worried about, or at least that's the point I got from the article. The thing we should be worried about is the way machine learning is applied in the here-and-now: the ethics of big data social networks, the robustness of complex (API-driven) systems, and so on. I fully agree that these issues are much more pressing and worrying than some emergent super-intelligence.
But I thought the article was weak in its discussion of dreams, creativity, and linear "flat data". It links to a June 2015 popular mechanics article about applying a genetic search optimization algorithm to discover gene regulatory networks, downplaying it as not-true-intelligence. But it does not mention deep neural networks and their higher-dimensional abstractions, particularly the psychedelic "inception" images.
The author also mentions "linear reasoning", and says he expects we'll learn more about intelligence from stem cell and Alzheimer's research, and the "tissues surrounding neurons, and the roles they play in contextual regulation." As if to set up some dichotomy between machine and biological intelligence. But what about deep neural networks?? I'm not sure how that would affect the author's arguments, but I'd like to see it discussed.
