# Summary of #hplusroadmap IRC Log (Feb 24, 2015)

• A discussion about black holes as computational entities took place, comparing them to "quiet M-brains" and referencing Seth Lloyd's "Ultimate laptop" paper which analyzes computing at the Bekenstein edge (http://arxiv.org/pdf/quant-ph/9908043v3.pdf).

• The paper "Closed Timelike Curves Make Quantum and Classical Computing Equivalent" (http://arxiv.org/pdf/0808.2669v1.pdf) was shared, exploring theoretical physics concepts related to computation.

• A study about developing painkillers with fewer side effects was shared from SLAC National Accelerator Laboratory (https://www6.slac.stanford.edu/news/2015-02-17-study-could-pave-way-painkillers-fewer-side-effects.aspx).

• A discussion about deep neural networks and their relationship to primate visual cortex took place, referencing a paper "Deep Neural Networks Rival the Representation of Primate IT Cortex for Core Visual Object Recognition" (http://arxiv.org/abs/1406.3284).

• Participants debated the concept of "representational power" in neural networks, comparing it to programming language expressiveness and discussing how different computational approaches may be better suited to different types of problems than biological systems.
