With this price for debt, IBM could be cash-flow positive on this deal within a couple of years even without any big synergy, just by the simple effect of cumulated growth on (net) income.

Permutation City by Greg Egan
Ubik by Philip K. Dick
Basically Pearl argues that classical statistics completely ignored the concept of causality so far and introduces a complete framework to bring causal inference into statistical/data analysis. The framework is based on graphs and asks for causal hypotheses (like econometricians would do with instrumental variables) and allows to compute/quantify causal effects.
Anyone working with data should probably read this book. The fact that Pearl brought in a professional math/science writer as co-author is a huge boost to the main ideas accessibility and make for a nice albeit deep summer read.

Edit: Actual Wikipedia entry = https://en.wikipedia.org/wiki/Insensitivity_to_sample_size
- scientific knowledge is embedded in some intellectual ether made of underlying hypotheses often not explicitly stated called paradigms
- paradigms follow a Darwinian evolutionary process, i.e. better paradigms evolve out of not-so-good previous paradigms
- paradigm replacements start with an epistemological crisis , i.e. facts that the current paradigms don't explain well enough.
Hope it helps !
Some things that are at stake on the lawyers side are their competence (can they actually make sure the contract is "secure" ?), their reputation (track record of competence established over time) and some insurance mechanism (if things go wrong can you get something back from their insurance).
All of the above seem to be missing in the case of "smart-contracts".
Ask HN: What do you do when your client asks for something stupid?
I work for a startup that sells consulting services on the side (software and data science). Sometimes I am asked by clients to do something stupid. E.g. running a clustering algorithm on 2D data where there obviously are no clusters (but hey the new segmentation is the result of a machine learning algorithm and the client likes it), or building performance metrics where we clearly have no...

It's also why phone services are so much more expensive in the US than say France.
The broad idea in (a) is to start with a fully connected graph, and eliminate edges between nodes that can be tested as independent, or independent conditionally on other nodes. This gives you a non-directed graph which can be oriented by several methods (identifying V-structures, looking at residuals of regressions of X on Y vs Y on X).
The theory in (b) actually generalizes instrumental variables and lays out graphical configurations where you can measure the causal effect of a variable onto another variable, and how to compute that effect.

It goes more or less like this:
- capital in search for long term returns goes to early moves of a big technological shift
- as successes from the new technology get more and more apparent, it attracts a much larger slice of capital available, and eventually gets over-funded (the real opportunity of this technology is limited)
- a bubble forms, most capital is in for a quick speculative return
- back to square one with a new technology (and former bubble bursts)

Piketty: Capital Predistribution and Redistribution
OpenAI is about more than saving the world
A few arguments that I can agree with though:
- Models are a compact formulation of complex theories. I remember a professor writing a dozen equations and claiming he just taught us Marx's Capital. In retrospect I think that's pretty funny, and quite telling of the superficiality that is rampant in the profession. But still that might have been a great executive summary (I still haven't read the book). Another example is Piketty's "r > g" that really is a lot of food for thought.
- Models can lead to actionable insight. I think there are people in Central Banks and Economics departments of governments who rely quite heavily on some models to forecast GDP, unemployment etc.
But this comes with a huge caveat: it's often easy to tweak a model to make it describe pretty much the opposite phenomenon of the one intended.
So the real benefits of that kind of academia were and still are pretty unclear to me. I believe some academics were hiding their lack of deep understanding of economic matters behind a fog of math. Even Blanchard (former chief economist at the IMF) admitted to something along those lines in the wake the 2008 crisis.
If they truly believe AI is dangerous, how does promoting / accelerating it is supposed to help?
Or is it a way to commoditize R&D in machine learning so that it will never be a bottleneck for startups?
