Cursor Is Lifechanging - A Thank You Letter

:star: :star: :star: :star: :star:

I am a humble, self-taught software developer. Though, recently I have begun to internally doubt that title. I’ve long since considered myself to be more of an “Integration Specialist”. I’ve been coding [just copying and pasting with my hand and my keyboard/mouse by my lonesome] for some 20+ years, and boy how I do wish that I had a graph that shows the lines of code written (by myself) over the years. There would be a very noticeable decline over the last year or two.

I do have sincere concerns about my career, in regards to how website/app development & maintenance will look in the near future… I feel like I’ve only just begun to show potential in my career and already I feel like I can see the light at the end of the tunnel. Regardless, creating and implementing solutions is a passion for me, and that’s unlikely to change no matter what. Anyway…

Cursor has singlehandedly (and, significantly) improved both my personal and professional life. While I do have constructive feedback (soon to follow), I would like to take a moment to appreciate how much Cursor has affected me. It has been a long moment since I have created a forum account simply to show my appreciation for a product, especially concerning one that I pay for.

I initially installed Cursor perhaps a year and a half ago, so that I could simplify the AI → Myself → Local Files gap. I broke the rear-view mirror off and never looked back. I believe Cursor was recommended to me by an acquaintance. I had tried AI for coding a few months prior to that but I didn’t have much success with it then. It had a problem with context and memory at the time.

I am writing here today to demonstrate my appreciation for this software and ask how I can help contribute (other than just financial investments)?

:red_question_mark: I’m also curious - what are the ways that I’m likely not using Cursor to its full extent? How can I fully embrace this? What should I be careful of? Am I overdependent on AI? How do you all recommend that I pivot in my career?

Please provide your responses in a format suitable for ingestion into Cursor…
