Bitcoin 1.0 probably won't happen in our lifetime.
I think it will happen in the next 15 years. I think bitcoin needs to achieve the following goals for it to happen:
- Throughput that scales and that can exceeds Visa transactions
- Better anonymity
- Low cost per transaction probably less than 0.02$
- Quantum computer resistant
- Mining solution for Bitcoin going forward without block reward
It wont be achievable on next 15 years because the things you listed is not achievable on a short period of time and it would really require sufficient years to develop bitcoin even more. Bitcoin 1.0 is not possible for me even though bitcoin would be fully mined but as we all know the last bitcoin will be mined took hundred of years. Are you sure you are still alive on that year?
