> Are they still a good use of time to write? No. If someone that matters reviews your resume, they won't care about the letter. It is something people write when they expect they'll be read by HR. In that case, you should write a single cover letter and have a few templated bits (the company, some parts of the industry they work in, maybe an anecdote related to those industries) that you swap out. Even that is IMO too much effort for something that won't benefit anyone but people not qualified to evaluate you.
