I know that in this case (and many other current ones) we're talking about older people but I don't think this type of scams will end anytime soon.
It will not. It is just going to be worse as crypto becomes more popular. More scammers will come out and more beginners might fall victim to those scams. It is high time that even as a beginner they know how to protect themselves.
It's the sad truth, we have to raise awareness but these scammers will keep on reinventing their scamming styles and they'll invent new ways of scamming people.
That's why us, as individuals have to keep on being informed and learning how to prevent ourselves being victimized by these cons. 
It is the least that we can do for ourselves and so, when something new comes out and seems familiar to us, that's how we'll disseminate the information to the others so they'll also be aware of it.
