Around 2009 or earlier, I began the long grueling process of creating my own batch AI (yes batch as in Windows Batch , kill me for not knowing there were better languages around). Looking back at it, it is THE messiest thing I've ever created. Mostly because of how many unnecessary files were created to make the entire thing work. However, I’m still proud of it to this day because of the dedication I had put into creating the entire thing.

I would create diagrams on the mirrors in my room; of course I would be scolded for this. But I was mad with thought working through the entire thing.

I would scribble and type whenever I had the chance, trying to create the functions that would allow the thing to talk back to me. Finally, when it opened its eyes and spoke its first words I quickly started creating the functions that would allow it to learn new inputs. Over time and with some elbow grease I was able to polish it up to my liking.

The entire program branched off some of my more earlier programs in batch, they mostly ranged from the medial to the crazy; i.e. turning my computer on and off at certain times of the day, and multithreaded migration of files to new disks

It's not as sophisticated as other AI that were being built at the time, but at the age of 16 and with no experience in real programming at all, I'd say it was my first stepping stone towards more sophisticated programs, and ultimately, my decision in Computer Programming at all.
