I was talking with my colleagues today that technology has changed now. I recall using Java in college. Now that C# and TypeScript have been used, we have used Server/Clients. Now, everything is in the cloud. However, I suddenly remembered the classic textbook Design Patterns, from my college days (more than 20 years ago). Technology has really changed, and it has changed a lot, but it is basically based on the same theory, and the Design Patterns in the book are used today.

I have been doing programming for about 20 years. Whether technology changes or signs of progress, I can adapt to it because the basic has not changed. If the basic has changed, and I have reached middle age, I really don’t know what to do to respond the changes
