So yeah, React may go away in three years. Do you think you would have been better off during those three years continuing to use jquery? Do you think the hours spent learning the new thing were more or less then the hours saved my the new thing having a better api?

(now, of course, you I may be wrong on the cost benefit analysis here. I don't think I am, and the ubiquitousness of the new stuff implies that most of the industry agrees... but no matter the answer, that is the way to think about whether learning something is worth it)
