Computers are really cheap now.
A PDP-8, the first really successful minicomputer (read very cheap minicomputer), was around 18,500 USD, in 1965's USD, or 170,000 USD in 2023's USD.
For a historic comparison, the price of a introductory minimal system for an actual "mainframe class computer" of the same vintage, a IBM System/360 Model 30, was 133,000 USD in 1965's USD, or around 1,225,000 USD in 2023's USD.
Those 8300 USD cited are very cheap.
A person in the bleeding edge of the private AI sector is expected to handle several Nvidia H100 80GB, each with a individual cost around 40,000 USD per unit.
Those 8300 USD cited are peanuts in comparison.
