I disagree. For this particular plant it is that dire.
I totally agree that Phalaenopsis are one of the easiest orchids to grow. They are forgiving as one learns how to care for them. But, when all the roots are gone, that increases the degree of difficulty. It will be at least 6 months before it has recovered enough to bloom. But it could be more then a year.
So for my money, I would toss it so I don't have to watch it suffer. And then maybe get a new one. Or get a new one and keep the old.
