I suppose emerging technology is always viewed in this way...
Why would we ever need any more than 640K of RAM?
Why the hell would I want my computer to be permenantly connected to the internet?
With technologies like this, you need to put the horse and cart the other way round. Throw the tech out there, and see what people can do with it.
I can think of a couple of minor uses for it (nothing earth shattering) but if the techs readily available, some bright spark will come up with something that'll make you think "Oh, yeah. Why didn't I think of that!"
It'll be nice to see GL get some DX support. It has languished a bit from lack of mainstream hw and sw support. The last ever game written it it was released 12 years ago.
Before the trolls jump on that, yes I know there are plenty of applications that use GL (I do raytracing myself) but we're talking numbers here, boys.
When it comes to native hardware support, GL really does need to tap into the readily available. After, who's gonna buy a £500 nvidia Quadro card to surf the web?
