I am masking nothing by writing several paragraphs. I'm making points that only seem to fly over your head. It's not personal at all. You continuously ignore half of the responses here and keep making the same stupid arguments like an idiot console warrior would, so the idea of it being rooted on a disagreement of opinion is long gone.
Valve aren't capitalizing on your dream scenario of making "at least a dozen" VR titles, when it took them years to create the best one yet. VR/AR is still not widely adopted and they aren't going to release games unless they're ready. They put in the work to support the ecosystem. Their attitude of building the tools and kicking the technology upstream has worked and failed in the market. As you say, Steam Machines, VR, Steam Controller were put out there and haven't taken off. Ignoring the successful growth of Steam and other things they are doing, it still all negates the points you're trying to make that they have done nothing.
So it seems you blame the market failures on the lack of software support now. OK. Again, stupid arguments leaning on the closed ecosystem, console warrior thought process, dismissing Valve's continuous growth, success, and actual software support on the back end that allowed them to try these things in first place. You cry about their impending doom, hand wave the defacto leader in the industry with "massive failure" talk, and praise old garbage like PSVR as some sort of benchmark they are losing ground to; and you wonder why people like me point and laugh why calling things stupid.
Valve never assumed the risk of selling a console under Steam Machines, they provided the ecosystem. OEMs tried and didn't want to keep losing money competing with their own products in the open hardware market. Steam controllers were an extension of that, and brought new ideas to standard controllers that anybody could use the R&D from. It wasn't hugely successful. Steam Link was successful enough and they rolled it out to other devices for remote play. They forked Wine into Proton and completely blew the doors open for Linux gamers.
"Valve does nothing" though. They are doomed. They aren't trying to sell us consoles, controllers, and VR headsets. PC is an open platform and they should be out there losing money trying to lock it down and shit on consumers like Epic Games, Facebook, etc. Right? Thoughts? Bubble wrap?
More childish insults hidden in a wall of text. I pity anyone that has to deal with you on a regular basis IRL. Ignored.
