Ye indeed they truly did become more sophisticated and you're right.
I made this blog to inform people, so they can have knowledge about something they have seen multiple times and do not know much about it, so in this article most of the stuff is explained, like history of invention , inventor , usage of it and more but i respect your opinion and on top of all, i totally agree with it so thank you for stopping by and glad i'm you enjoyed it.
