2035 growth plate implant (alternative to LL without side effects but you still need to use the metal fixators)
2042- AI with the same level of intelligence as a human
2042-longevity escape velocity for billionaires
2050- transdifferentiation of bone to hyaline cartilage (growth plate) with nanobots to grow proportionally and in a non-invasive way
2050- affordable hyper realistic human-like female robots
2065-singularity
2075-2080 affordable anti aging.
I don't think we would see reverse aging until the next century or it may come faster thanks to the singularity.
I say 2065 for the singularity because ray kurzweil was wrong about the technologies increasing in speed every 12 moths, it is really every 18 months.
For example he predicted self-driving cars by 2010 but they will come by 2025-2030. You just have to multiply Kurzweil predictions time differences from 2005 by 1.5x.
