Do we still need to build wheels?

When I discuss the technical details of "bottom layer" with some friends, they are often "super masters" (from Mars)
The irony is to make the wheel, and I always smile. Because I say what you are doing is just a fact, and this world does not
Any criteria to judge whether this behavior is correct, maybe only God knows.
 
Do we still need to build the wheel that has been invented by others?
Of course we need to add one or two sentences in some comments about the "Masters" who make the wheel:
IT technology in China is because your talents will never catch up with others.
Let's look at this kind of contradictory master's point of view. Since we are opposed to making a wheel, many technologies have been invented by others,
Why should China create another wheel? So far, these projects are meaningless, and the country has spent so much.
What makes money only the wheel invented by others many years ago?
 
In fact, building a wheel is meaningful and necessary too often, because the wheel made by yourself
The words are the most appropriate. or raise a point to say that I think I made the wheel of others' good. If you have the ability to make the wheel, and
I can't find any reason for not building a wheel.
Save time? Not necessarily, you have to buy other people's wheels from home to shopping mall transactions and then transport them back.
The wheel maker is enough to create a wheel that is more useful than the wheel we bought.
For example, anyone who downloads smartupload for the first time, reads the document, learns how to use it, and obtains
The testing time in your code is no less than 30 minutes, right? However, for those proficient in HTTP protocol, the client is packaged and submitted
It takes 30 minutes to break down the unsigned Character Sequence into fields and files. That is to say, I have implemented
But the self-implemented wheel must be at least easier to call than the general wheel debugging, let alone modify it.
In addition, I can easily "translate" my own implementations into other languages, for example, I can spend another 20 minutes
To implement the Upload Component in C #, how long will it take to translate the smartupload wheel into C?

If your capabilities are not enough to create a wheel, you certainly do not have to study how to create it when you need the wheel.
But if you can build a better wheel within the time you have bought the wheel, you should firmly build your own
Your wheels! Therefore, whether or not to build a wheel depends on your accumulation of knowledge when you do not need the wheel.
It can be created as needed. It is faster than buying a wheel, and the quality is better,
This kind of wheel building is really not funny. In my mind, it is the highest realm of software technology.
