jQuery has helped me tremendously in the past and continues to do so. Not everyone has to design a website like google.com and not everyone needs to take into consideration every byte that is loaded in a web page. A library that gives you a single way to do things that many browsers support in a less verbose form is just amazing tbh.

At the end of the day when you need to just get things done jQuery still shines. Does it produce spaghetti code? No, you are doing it. Does it become an enabler in spaghetti code? Yes. But not all the use cases are the same.
