The way I view Steam Machines is just as a delivery system for SteamOS. I don’t know if Valve even thinks Steam Machines will themselves be successful. I’m thinking they are betting on enough users adopting Steam Machines that they will get a foothold with their OS and start pushing Microsoft out.
And that kinda makes sense as Microsoft is going the “AI first” route and focusing on productivity. That leaves an opening (if albeit a small one currently) for companies like Valve to pull users into their “Gamers first” SteamOS.
This is akin to the “boycotts” people have done against gas stations for high fuel costs. It doesn’t work. It’s always like “on a Tuesday, don’t buy gas”… but you weren’t going to until Friday anyway. And then you buy it on Friday, the books balance exactly the same, and there is zero actual impact.
You want to impact Sony? Stop buying games on PS5. Not for a week. For this entire console generation.
