That's a three years old article, is it even valid today? It basically said NVidia should drop legacy support.

No. cpu physx is not broken and it's not crap. cpu PhysX is intentionally crippled (not optimized) so that the gpu version is much much better.
cpu physx performance will never come close to gpu physx performance (unless cpu is very strong and gpu is very weak) for hardware reasons and because nvidia's main business is gpu.

PhysX discussion is headed off-topic. Point is ....
CUDA could be more useful if there is a cpu version which allows compatibility with non-nvidia hardware.

Why should Nividia support competitors like Intel or AMD? What if they build a CPU/GPU that's more cost efficient at running CUDA than Nividia's own GPUs?

its similar to the answer on why game devs still make a DX9 version of games. To cover a large majority(XP users+) so that as many people can play/use the software. With a smaller base, comes less of a large community. Only one company has jumped off the previous versions of DX boat and that is Crytek with Crysis 3(Dice should also be jumping after BF4). If not as many people can run the software, less people are inclined to work on a project involving it.

May the best technology win on its own merits. If you don't build it, someone else will.

Please generalize more.

Good programers are those who persevere. If everyone quit because they didn't have talent, they would never get talent...
