ELI5: Why was cloning such a big deal in the 90's but now is rarely spoken about?

Does it not seem that cloning would save a ton of endangered species?   What happened to cloning humans?

There were a lot of breakthroughs in the '90s, and that made it new and exciting and a big deal. And naturally also very blown out of proportion. 

There are still advances being made, but nothing huge. 

Cloning would not make a species viable, either. You need genetic diversity, which is the exact *opposite* of cloning.
