Communists are, technically, atheists. China is a big region. Surely, atheists can call it home.

This is second successful trial of autonomous vehicles in traffic we've heard about (the first is Google). It's clear that technology is viable. It's clear what benefits it will give.

The arguments against this technology remind me the early days of the Web: it was widely believed by skeptics that no one will ever use the Web for commerce because (1) there's no framework for financial responsibility, (2) internet backbone is closed for commercial traffic, and (3) there is no accepted technical solution for HTTP encryption, and encryption packages are considered controlled technology by US government and are prohibited to be freely distributed. All these objections were solved or waived in a couple of years.

None of the described future attacks are feasible. Shared framebuffer is not accessible to applications directly for security reasons (authors think that this is "unfortunate"); direct access to framebuffer is not "inevitable" in the future -- much better technique is to use driver-controlled fast GPU blits: data doesn't leave GPU. Non-timesharing is non-issue -- driver can detect timeouts and reset hardware (TDR on Vista).

So the only issue is polymorphic virus that may use GPGPU decryption. If this happens, scanners will start using CUDA, or GPU virtualization.

Many (all?) modern GPUs have virtual addressing with page protection. Switching is handled by kernel mode driver (we are talking Vista+) and is not controllable from user space. Now we are talking KMD attack which is not different in principle from any Ring 0 driver code attack. Good luck!

Computers will not be perfected until they can compute how much more than the estimate the job will cost.
