"The problem is that most algorithms and program logic cannot be made to run better across many processors" evidence for this? I was hoping to hear him talk about the Von Neumann Bottleneck (http://en.wikipedia.org/wiki/Von_Neumann_architecture#Von_Neumann_bottleneck http://en.wikipedia.org/wiki/Von_Neumann_architecture#Von_Ne...), a problem faced by serial and parallelizable algorithms.
