My Stance on AI in Programming
Disclaimer All of the thoughts below are personal opinions, they’re not sponsored ones (I’D SURELY LOVE BEING SPONSORED but this blog has somewhat like 2 readers), the AI usage here is close to 0, with the exception of the grammar and style review, as the author can’t type 4 words without making a grammatical mistake. A lengthy intro AI is polarizing. People are in love-hate relationship with it and there are obvious reasons for that: fear of jobs being taken away from humans, enormous amount of AI-slop in every media format possible, endless AI-first solutions for non-existing problems, VCs pouring billions into AI solutions, endless AI-written linkedin posts about the bright future of AI, you all know it, it’s fatiguing.
