I am sorry. In memory of, once, a site I just want to quote this. There is nothing to add:

The more I look at such things — computers in several rooms size, a few bytes elephant size PC, keyboards with huge leverage and connectors like in the photo, the more I admire the people who created it all.
But to the dumb ones, to whom this seems ridiculous and useless compared to your shit phones, I will say – these are stages of computer evolution, without which there would not be, and could not be most of the technology in your surroundings.
If the post is built in violation of the logic, I am drunk.
