I have a 4090 (24 gb vram), 32 gb of ram (DDR5) and 12 tb of ssd memory.. I'm seriously considering taking out an insurance policy on my computer.

I was looking at buying another Xbox one because they are so cheap for work with firefighting simulator, would have upgraded the internal spinning rust drive to a 1tb Sata SSD.

...The SSD costs more than the second hand console, even for a Crucial/Western Digital drive.

$180 AUD for a 1tb Sata SSD.
$130 for an Xbox One.

The AI bubble can't pop soon enough.

The AI bubble will burst eventually, and prices will come crashing down. In the big picture, prices (in constant currency) will likely go lower than they were before this big run-up, because of the increases in manufacturing capacity coming online now and in the near future.

The same will probably be true of RAM and graphics cards, so long as the AI bubble bursting does not coincide with another big crypto boom. 

I doubt prices will end up lower than they were before... Because of several factors.

Firstly... The new capacity is mostly for HBM memory, not DDR4/DDR5 or the LPDDR variants.
HBM requires more wafer area for it's memory as you need to stack the chips plus account for the inter-poser, so it's a zero sum game... New capacity, but not increasing output in terms of capacities as it's invested in bandwidth gains.

Secondly companies like Micron has already shifted it's entire company to focus on data centers and servers... So that is already a blow to consumer prices due to less competition.

Thirdly... There is a backlog of orders that will need to be fulfilled for automotive, industrial and embedded designs... Think signage, gambling, ordering kiosks, satellites, smart devices and more.

Fourthly OEM's like Dell/Asus/Lenovo/Samsung/Apple/MSI and more will likely gobble up all excess supply if it even enters the consumer market.

Fithly, legacy production like DDR3 and DDR4 are slowing/stopping, but there is still a demand, so those markets will transition rapidly to DDR5 or newer in order to continue securing orders, which will take supply away from the DDR5 consumer market.

Sixthly... The new capacity will not be operational until around 2028.

The market is stuffed. It's going to stay stuffed for a long time.
Those who will win are the DRAM companies... But even Samsung is forecasting much of it's business (I.E. Phones, watches, tablets) to reduce in sales as consumer electronic prices soar due to DRAM, but that's offset by improved DRAM profits.

As for Crypto... Crypto booms tend to coincide with a corresponding increase to compute.. That has slowed.
We also had the Ethereum Proof-of-Work to Proof-of-Stake merge, which completely decimated the profitability use-case for mining on GPU's.

Plus the data-center/A.I boom is having a corresponding impact to energy usage across the globe, which means energy prices are rising, which means that GPU mining is less viable.

Then we need to factor in nVidia reducing GPU production for consumers resulting in price rises, which also destroys the financial viability of crypto-mining on a GPU.

My advice is, try and make your PC last as long as possible and jump on a new GPU now if prices haven't risen much. It's here to stay for awhile, might as well get comfortable.

On the bright side... Even low-end hardware is stupidly competitive with consoles, so you can get a very respectful gaming PC for very little coin if you play your cards right.

I.E. Ryzen 5000+DDR4+RX 9060XT.

Wasn't there recently some game that went like from 150gb down to ~22gb or something, because a team decided to optimize it and remove reused assets because of old HDD loading requiring duplicates of stuff for reading speed? or something silly like that. 

Yes, Helldivers 2, although I think it might've been 80+ GB instead of 150 GB. It was very impressive nonetheless.

It was on PC.
The reduction was also from 154GB to 23GB.

And this works on mechanical hard drives, in-fact it improves performance on mechanical hard drives... Because moving a HDD seek head over a platter is much easier and quicker to do over 23GB worth of sectors, than 154GB worth of sectors.

Plus, again, developers don't get to choose where the data is stored on a god damn HDD anyway... Nor can a game demand the HDD load assets from the center of a platter or the outside of a platter for optimal speed, there isn't that kind of transparency and control between hardware and high level software.

I have all my PC games stored on a mechanical HDD unless the game/engine demands the IOPS (I.E. Cyberpunk) or it's a game I constantly boot and play. (I.E. StarCraft 2.).
Helldivers 2 did load and run better on my mechanical HDD with the removal of duplicated assets... But I have a 40+ terabytes worth of storage, so there is some fragmentation of data anyway... And the smaller your games footprint, the less fragmentation you will see which results in better loading.
