There's some validity in this claim, although for the sake of debate, I'm only going to refer to my own purchasing and use habits.
So the XB360 came out in 2005, but I didn't buy one until almost fall of 2007, after buying a PS3 in January of that same year.
By about mid 2008, I transitioned over to a DIY gaming PC for the cleaner resolution and slightly smoother frame rates. Mid tier builds don't provide both max res and max frame rates on current games; you either play with the trade off/balance or you spend a lot more on GPU(s).
The XB360 was more or less abandoned for the Windows/Steam gaming PC, but the PS3 continued to see regular use for the exclusives and as a general media player as BD hadn't been replaced by streaming until far more recently.
Today, if I wanted to replace the PS4 for gaming, I'm looking at spending about $400 on a GPU that would make it worth my while (GTX 1070) on top of doing a new build, which is necessary if a desktop PC isn't one's primary system that sees regular updates. I work on laptops.
Contrary to popular PC rhetoric, you can't keep grandfathering PC parts indefinitely; eventually they all have to be upgraded to keep the overall system balanced. So that $400 GTX 1070 would actually cost me about $1000 for a balanced system build.
Or, I could just buy a PS4 Pro.
Would it be the same? No. Obviously a GTX 1070 driven PC is going to perform better and will offer more flexibility and I would be able to double it up as either an extra editing PC or rendering PC while I work on a laptop. But if I was just using it for gaming (which I wouldn't), $400 worth of hardware doesn't get me there.
So if I want to start gaming on a 4K display, then yes; the PS4 Pro would stop me from switching over to gaming PC, which took me less than two years into the 7th console gen.
