Ask HN: Does modern software development require too much knowledge?

Software development requires continuous learning it may be new technology/language methodology or a complete new platform so Why only 4 Years , In my opinion as software developer you are a student always, you need to continuously increase your knowledge and its practical implementation; technology comes and goes so you need to be adaptive.Yes it always takes some practice experience to build something valuable but you can always start with something very little and working and then build as you improve your knowledge and skills. So be open minded learn something new every day and build valuable things.

If you're having fun, seeing the possibilities instead of limitations, eager to experiment and learn, then you won't even notice. Find what you can do, do it well, learn how you can do it better, and it will all come into place.

I've heard it said that software development knowledge has a half-life of 3 years. That means you'll forget half of what you learned 3 years ago. That means half of the stacks that are relevant today are going to be gone in 3 years. What doesn't leave is your ability to learn, how you do things, your approach to problems and your priority.

Keep dreaming and visualizing what you want to create. You may not see how what you're doing today is ever going to materialize into something, but at some point everything will click and you'll be building what you want.

> four years intensive learning and practical experience under your belt.

You're not even finished after four years. In fact, you're merely starting.

It is true that to succeed the modern developer requires an enormous skillset. At the same time, everything is so accessible because of places like Github, IRC channels. There are a wealth of tutorials covering every topic imaginable, sites like StackOverflow giving you the opportunity to have your problems solved, and a community of developers who truly want to help fellow developers.

Because everything changes so fast in software, in the developer DNA must be built in the ability to master new concepts and apply them very quickly. You build a solid foundation and can apply it everywhere. Additionally, in software development, you reinforce the skills that are important because you use them. You learn as you go and must always be learning.

And for some perspective, think about how relatively easy it is to become a developer vs. getting a PhD.

I think development of software will continue to get "easier" as languages, technologies and ideas evolve. I think over time these technologies will get to the stage where you barely have to think about the technology in use, and rather just focus on the problem at hand/what you want to build; this really is currently the case only after years (or decades) of experience and purposeful practice.

The current development of software does require a lot of knowledge to break into the market; however this also means that software development is a skilled profession which leads to higher than average salaries.

I would also add that we are seeing people enter the software/web dev market without a 4 year degree. A lot of people that I know have done 2 year diplomas and even compressed 4 month "bootcamp" style programs
