Why are computer chips getting expensive day-by-day?

Chips are getting expensive by the day because of these reasons:
Chips are made from silicon (which serves as insulator) and metals (use as transistors). Silicon is not expensive but metals are, over a billion transistors are packed into a chip.

The increase demand for larger and more advance chips and the limited supply of these chips drive up the price of chip in the market.

Most manufacturers spend huge amount of money doing research on how to advance the chip and also make it more efficient. They recover the money spent on research from the sale of the newly developed chip. Do not forget that they are chips that are not expensive in the market. It all depends on the type and quality you want.

Computer chips are getting more and more expensive because companies can load more and more information onto them with each passing day. This information could be in the form of memory or software. It is also important to note the sizes of these computer chips. With each new model produced they are becoming smaller while carrying the same amount or more information. The smaller something is, the harder it is to work on, which means more qualified labor or more expensive robots (which cost money to build and maintain.)

And of course, when a new product hits the market, it is automatically more expensive. Think back to floppy disks—when they first came out, they were costly. They only carried a certain number of megabytes. Now, we have jump drives that can carry terabytes that are a fraction of the size. For that technology to continue to develop, people have to show a need for it by paying for it.
