People who work on the user interface side need to have empathy as a key characteristic. But if you are writing device drivers you don't really need to understand humans so well.
Among many other things, a smartphone functions as a handheld digital sensor for the physical world. In other words, we don't necessarily need our real world things to be directly connected, when the Web interface in our mobile devices provides the network access and intelligence.
Every day, hundreds of millions of people stab themselves, bleed, and then offer, like a sacrifice, to the glucose monitor they're carrying with them. It's such a bad user interface that even though in the medium-term it's life or death for these people, hundreds of millions of people don't engage in this user interface.

A picture is worth a thousand words. An interface is worth a thousand pictures.
Steve Jobs' ability to focus in on a few things that count, get people who get user interface right, and market things as revolutionary are amazing things.
As computer intelligence gets better, what will be possible when we interface our brains with computers? It might sound scary, but early evidence suggests otherwise: interfacing brains with machines can be helpful in treating traumatic brain injury, repairing spinal cord damage, and countless other applications.
My list of basic tools is a partial answer to the question about what has changed: Over the past few years, large numbers of programmers have come to depend on elaborate tools to interface code with systems facilities.
I have learned to interface - what I think would be the contemporary term - with various different lexicons, and people speak very different languages. I've learned to speak in a lot of tongues, and I can live with the bellicose language of some fervent, fire-breathing Christians, sure.
