One of China's largest chip producers is building several new fabs and their domestic fabs (i.e. ones not made by ASML) are capable of producing DDR5. Once this price shock ends I wouldn't be surprised to see hardware prices drop to below levels they were pre-2020.

What we're seeing is the effect of companies having hundreds of billions of dollars in cash on hand and all deciding to dump it into computer hardware at the same time. They can't burn capital forever and AI isn't remotely what they're selling it as so they're finding a hard time generating any meaningful revenue. All they're doing is shoveling money to hardware manufacturers, who will use it to build out extra capacity and once the spending frenzy ends we'll have way more supply than demand.

Of course, given how much money is floating around, that could be 5 years from now.
