20-30 years is very very optimistic prediction. They imagined flying car. It will be the same for self-driving car. Although we did lot research and progressed by leap and bound, we still face ton of challenge as tagged traffic sign recognition, unpainted road...it's not ready and AI is not able to understand our environment, nor able to do any ounce of adaptation.

We are in a very early stage. Their main asset is finding the correct data and copy-pasta. They can't think.

I wouldn't put any cents in neuralink : this technology already existed and created a connexion between a brain and computer. Nothing more. Musk is only an investor with a sprinkle of personality cult.

We are very far from understanding how brain work, nor illness as depression, bipolar…and that doesn't mean we haven't progressed but we are very far from this step aside connecting brain to computer and moving a mouse on the screen.

If we succeed in memory transfert, there is still lot challenge to solve. We know nothing about our brain and memory.

When you transfert memory data, we will need to make sure various point :

• that we are able to create new memories, think and use the data received
• that we can solve possible memory conflict between old brain and new brain.
• that the data transferred last.
• Is the clone another version of yourself ? It maybe someone else with a different habit. In fact, you died.
