Predictions for future watering down of HW titles

This decade in HW boxing we have seen - One titlist who has normalised fighting men in their 40s. Another who got beat by a fat boy. A final one is referred to as a great but is yet to make a single defence. What will be your predictions for the 2020s in boxing? Will we see world title defences being made against men in their 50s or 60s? Title fights reduced to 8 rounders to accommodate increasingly overweight contestants.
