Stable tokens will have a future anyway. This is normal because stable tokens must retain their value. I hope that cryptocurrency will have such an opportunity, especially if we use it with you today.
You are right that the stable of coins has a future, but it is important to understand that only a few coins have it. I think that in 3-4-5 years there will be only 2 stablecoins.
It has a future when it's backed by a real dollar but it has no future when it was avoiding any audit just like tether when it has stated if the company maybe didn't have enough dollar funds to back the total USDT that already available in the market.
