Why can't I use "to the point that" here?
"If you're anything like me, I'm sure you've found yourself, at one point or another, feeling trapped in this endless loop of work and play, week after week. And it gets to the point where all that matters is how we reward ourselves after a tough week at work."
I thought "to the point where" and "to the point that" are always interchangeable, but the lecturer said that you can't use 'that' because of the context. Is it true?
