timppu: Pure marketing talk. They just want to push their vision as much as possible (to sell something), suggesting that the (old) alternatives are only for silly people who cling to the past.
It is a bit like when MS was pushing its earlier Surface tablets, one MS executive suggested that in the future hardly anyone wants to use a keyboard anymore, only some nerdy programmer types. Rest will use exclusively touch controls, motion detectors, speech recognition etc. for all their needs. This was their marketing for the "new" Windows RT Surface tablets, so that e.g. PC users would move to use them (didn't happen).
Yet, nowadays it seems more and more common that high-end tablets come with keyboards. Odd?
Yeah, computing tech is another perfect example of what I was talking about with market trending more towards splitting than being supplanted. I know the entire IT industry was in a frenzy about how tablets would make the PC obsolete, and it's never come to pass and doesn't look like it ever will.
It's the same prediction that industry pundits made when laptops came about, that the days of the desktop were numbered. The quiet dissenting voices pointing out that laptops could never achieve the performance of desktop were openly mocked and pushed to the side, because it was a rational view that wasn't profitable, wasn't sellable and wasn't newsworthy. And yet, 20 years later, here we are.
That's not to say tablets and laptops don't have a raison d'etre - tablets are superb as consumption devices and for simple games, laptops for creative processes where the user has to move around a lot or only has limited space. These solutions offer benefits but compromise on certain features to achieve these benefits.
So I'm sure streaming will find its niche for in-home solutions, gaming rentals and demoing, but when local gaming is an affordable, technically and legally superior alternative, there's no way it's going to be replaced by streaming just because the industry wants it to.
