There are too many emojis and they are too poorly defined. The Unicode Consortium has done a really bad job. They need to make sure the meaning of the emoji is clear. They should clear out the cruft of the last decade and start again.

Yes, but it won't happen.
As far as I understand, lots of the original unicode emojis were created to match proprietary symbols from different companies, so there was always going to be some overlap.
But, we can't use 100 emojis of very slightly different facial expressions. 😵💫
