That's not true at all.
What has become more expensive is Youtube glorified bleeding edge parts.
Ram is about the lowest it's ever been, drives are at the lowest they have ever been, ssd's are cheap (and rapidly falling), and processors? You can get insane power for prices similar to what they have always been, meaning they are cheaper than ever for so much power. Even in the case of GPUs, as always you can get a pretty good card for under $300. So long as you are not using high refresh, 1440(3k) or 4k, a GTX 1060, 2060, 580 or 590 will run just about anything quite well. You don't really
need a 1080 unless you're using this stuff and if you are, then the rest of your system needs to be equally high end. They call it bleeding edge because it hurts to buy it and you will be able to get the same performance next year for half the price and it may need revisions before it works like you expect (*cough* RTX).
As pretty much always, today is pretty much the best we have ever had it in computing.
It's only gotten more expensive at the bleeding edge because companies realized people will pay for pretty much anything they offer if only for bragging rights (look how many bought the Core I7 8086k processor, which was a factory overclocked 8700k), the normal stuff is cheaper than ever and in many cases I'd even argue that the higher end isn't even really much if any more expensive. When I first got 16gigs of ram 6 years ago, I spent $300 for it, I bought 32gigs for about the same price recently. My 8700k, cost exactly the same as much as my 2600k, both high end core I7 processors, 6 years apart. One thing that has changed is Youtubers getting free parts and acting like everyone has a GTX 1080.
They don't.
By the way, if you don't think things have progressed... It used to take several minutes to boot Windows or Linux. My current system cold boots to desktop in about 12 seconds, all but 4 of that is bios and the OS ensuring a dependency that preceded it was running. You may be thinking that is Windows Fast Booting, nope, that only takes 6-8 seconds 4 or 5 of which is bios and dependencies. Compare that to the average desktop from 5 years ago without an SSD, which took 45 seconds to 3 minutes depending on hardware and software installed. Even installing it used to take 45 minutes to install Windows, even on a high end system, today I can do it in about 10 minutes.
