I used to be a utilitarian 15-20 years ago after reading the work of Peter Singer and many others. These days, I have to admit its application has been almost without exception backwards if not reprehensible. It seems to lead inevitably either to (obviously repugnant and utility-destroying) communism or a strangely twisted and fruitless hyper-rationality (think contemporary Effective Altruism).
In the end, and perhaps in service of my original utilitarian impulses, I feel that entirely abandoning utilitarianism is the right path. This is sometimes referred to as `esoteric utilitarianism`, something that Sidgwick wrote about — suggesting that even teaching people about utilitarianism (himself being a utilitarian) might be immoral. Virtue ethics has been particularly appealing!
