> Portability is not possible. Real applications are closely coupled to hardware. Change the platform and all the code changes

Some lessons simply did not age well.... Even in world of today's microcontrollers, which often have kilobytes of RAM and very different CPU styles, people still write mostly hardware abstracted code.

It's the usually game of MPUs becoming cheaper or more stuffed for the same price because the demand allows to manufacture bigger batches, and the demand is to allow more portability by the means of more stuffed MPUs that allow more abstractions...

But it's a miniature of the same tragedy as Node.js applications that consume ten times the resources needed just because it allows people to do more with more... In a logarithmic way.

Most code should be abstract, because the things that are specified are abstract. Some code needs to be closely coupled to hardware, but most code should only need to be closely coupled with other code.
