If everyone accepted this fallacy, nothing would ever get built.
> Nothing about this attack is going to impact the effectiveness of ASLR in the cases it was designed for.
Then you said:
> This article makes it sound like ASLR has been completely defeated, but it's only defeated in a context where the attacker has significant control - even if that's a likely scenario.
That is indeed a highly likely scenario, so it's simply wrong to say "nothing about this attack is going to impact the effectiveness of ASLR".

That is actually an intended purpose of many social widgets.

1. Commit fraud on a massive scale
2. Say "I accept responsibility" but fire subordinates
3. Ride off into the sunset with obscene personal wealth
This coming at you from behind is not all that different to a motorbike, is it? You'd have a special traffic light phase at each end to allow it to loop around safely. This has to be much cheaper than digging tunnels anywhere where earthquakes are a concern.
edit: I'm being downvoted for this, but I wasn't using "belligerent" negatively here; I was wondering aloud whether Tesla's characteristically aggressive approach to damage control is the result of direct involvement from Musk. Doesn't seem that crazy to imagine that it is.
I interpreted this as being one of them.
> What must be understood is that in all these constructions, each circuit gate must map to an instance of Gentry's fully homomorphic encryption scheme, and at every clock cycle for the obfuscated circuit, all gates must be processed, regardless of whether they are "active" or not in the circuit (this is a big part of why the obfuscation theoretically works: it does not reveal active gates, by always making them all active). This[2] article gives performance result: on a rather big PC, we are up for minutes of computation. That's for each gate in the obfuscated circuit, and for each clock cycle.
> There are millions or even probably billions of gates in the envisioned circuit, given the setup of functional encryption: the "obfuscated circuit" must include asymmetric decryption and validation of zero-knowledge proofs. So now we are talking about using all the computers currently running on Earth, all collaborating on the computation, and they might make non-negligible progress towards running one instance of functional encryption within a few centuries.
Privacy and key loss are two reasons that come to mind.
