I feel this way about machine learning. Back when I was a high school student around 2010-2011, I really fell in love with classical AI and classical NLP, which led me to focus on these topics in college. By the time I graduated in 2017, deep learning had taken over, and while the results speak for themselves, I really don't have the same passion for it as I did working with tangible concepts like HMMs, probabilistic graphical models, Bayesian nonparametrics, etc.. It's tough falling out of love with your field.
