Of course. There are many human made subs that suck too. For example when Shikanoko came out the subs were quite bad but clearly human made. But the positive about subs is that you can still hear the original Japanese so you never have to trust or rely on them completely. I always take things from listening that are not in the sub. If I were just to read the sub I would miss many things. With dubs you don’t have a choice, you just have to trust them. AI dubs would be even worse.
