There are two twin evils that I see in the programming community. The first is the programmer who knows what he knows and has no desire to learn more. I call these, “coasters”. And then there are the programmers who are so curious that they try to learn every new thing that comes along, with no focus. The interesting thing is, both of these types of people end up at the same place. Out of work. The cure for both is the same. Being Awesome.
The first time a programmer who was trained in the classical procedural/object oriented history is confronted with the concept of making everything immutable, the first question that comes to mind is, “won’t that make my application slow?” This is because of how most programmers have been trained. Making everything immutable generally means that we must copy a lot of memory from one place to another. Moving memory around is generally considered slow. And so, most programmers dismiss the whole idea as crazy talk. But is it really all that crazy?
Another place I see this is with the recent announcement from the Angular team stating there will be another major point release every six months. Like this is a bad thing?
And I look at that and honestly wonder why these people are programming in the first place. If change bothers you, you are really in the wrong industry.
