Jerry seems to be happy that few changes will be made and
There are two options when you are so obviously proven wrong. Change is option one and the one that leads to improvement. This option takes character, courage, self awareness and the desire to improve things. The other is doubling down and continuing in the exact same manner because you can't admit you were wrong or because you are completely incompetent. This option is driven by insecurity, incompetence or ambivalence. In Jerry's case it might be all three.
