Now, for interpreting the Donald into JC intelligible language:
The first sentence is ignorance at the worst, poorly worded but somewhat correct if given the benefit of the doubt (i.e. you interpret "to fly" to mean, click, click, handfly*). The second is sarcasm, sorry, no free degrees today. The "unnecessary step further" is what he should have left to the experts, apparently the MCAS was a necessary band-aid because of changes in handling characteristics. The rest of the tweet(s) are accurately and, if said by anyone else, would be lauded with praise for explaining why pilots are still around and needed. The whole premise of the tweet, though, is flawed if taken in the context of the 737 MAX controversy.
