2017 estimates were based on Tesla's belief automating everything would work. They tried, it didn't, and they went back to doing more manually.

 That's not how it works. you can't just make a token gesture and say 'welp didn't work guys sorry! Thanks for the billions of dollars in capital though!'  
  
 You have to make actual investments in actual technology that has a reasonable chance of doing what you say it will do.
