Off topic: Unlike many out there I'm not usually bothered by lack of capitalization in comments or tweets, but for an essay like this, it makes the paragraphs so hard to read!
If someone can't even put in a minimal amount of effort for basic punctuation and grammar, I'm not going to read their article on something more sophisticated. If you go for the lowercase i's because you want a childish or slob aesthetic, that can be funny in context. But in math or computing, I'm not going to care what someone thinks if they don't know or don't care that 'I' should be capitalized. Grammarly has a free tier. ChatGPT has a free tier. Paste your word slop into one of those and it will fix the basics for you.
