I think regretting Mac upgrades is a real thing, at least for me. I got a 32G Mac mini in January to run local LLMs. While it does so beautifully, there are now smaller LLMs that run fine on my very old 8G M1 MacBook Pro, and these newer smaller models do almost all of what I want for NLP tasks, data transformation, RAG, etc. I feel like I wasted my money.
