However, if we are inventing, the design from the scratch is a better option as you need that though much work is already done, and hence you will get the pre-built components from the market quite easily and surely. Hence, building from scratch is not a good option anymore considering the above-mentioned reasons if we leave behind invention, and at times deep research factor.
