"Hey" is the single most common opening message on nearly every dating app, and it has the reply rate you'd expect from something anyone could have sent to anyone. The problem isn't laziness exactly — it's that a generic message gives the other person nothing to respond to except the fact that you exist, which isn't much to work with.
What gets a reply is specificity: a reference to something in their profile, a question that can't be copy-pasted into the next conversation, some evidence you looked. It doesn't need to be clever. It needs to be about them.
This is also, not coincidentally, where a chart-based opener earns its place — not as a gimmick, but because two people's compatibility read gives you something specific and true to open with that isn't just "I read your profile," which everyone claims and nobody demonstrates. The mechanism is the same either way: specificity beats wit, and wit beats nothing, and "hey" is nothing.
