That is only his opinion. CUDA has much better documentation, and support, than OpenCL, that is no question. But from compute CAPABILITIES perspective, they are the same. There is nothing that CUDA allows that OpenCL could not allow. Unless you believe in Nvidia magic. But the implementation and running software on it is easier.
P.S. Great to know that VMware praises Nvidia for their marketing efforts.
"There's nothing CUDA allows..."
Well, except a full line of products that perform much better than the equivalent AMD product.
I'm hoping Polaris FirePros knock it out of the park,
But I'm not holding my breath.
