Programs are a lot more complex. The computers aren't.

They were far less homogenous in the early years. Today you have a octet addressed little endian integer machine, with ieee float hardware and a small vector unit. Maybe you have two different instances of that on the same address space, but probably just one.

I think reasonable argument could be made that the complexity in modern computing is primarily self inflicted by software engineers.

Computers have gotten much more complex. Maybe your OS provides that nice little bubble for you, but it’s an illusion
