The only issue I'd have with this is that you'd be very overweight on one signal; that has a lot of data and context to give compelling advice of any degree of truthfulness or accuracy. If you reflect on your own life and all the advice you've received, I'm sure lots of it will be of varying quality and usefulness. An LLM may give average/above-average advice, but I think there is value in not being deeply tethered to tech like this.

In a similar vein of thought to "If you meet the Buddha on the road, kill him" sometimes we just need to be our own life coach and do our best to steer our own ships.
