Coding is important since every technology we use probably has some code running in its background. I think we should understand how technology works because it’s part of our life. Likewise, we learn math because we need to know the mathematics operations, which is a helpful knowledge in our routine.
Besides, coding can help you a lot to automate simple tasks. People have already been automating tasks using Microsoft Excel which is an excellent and nontrivial tool. I mean, we need to spend time to learn the Excel features. Coding is similar to Excel but in a lower level of abstraction. You need to know the basic details about computer science to create some code.
The author said that people can learn programming in 15 minutes or less per day. I disagree. Probably people will spend more than 15 minutes a day to learn how to code. The first 15 minutes is the time to start to concentrate and setup the tools you might need.
If you want to learn to code, dedication is important even if you don’t want to be a programmer.
