Being able to see something and replicate it yourself is a hard or easy skill to acquire depending on what you are trying to replicate. I like to challenge myself, so I find a Lego and try to make an exact replica on Lego Digital Designer which is a Lego software with virtual bricks. However, we must not replicate any written word or content that belongs to someone else because that would be plagiarism.
Replication can be good or bad depending on how you use it.
