That is the solution. We see what you are describing with aerial drone displays that are popular. To create a photorealistic human would take hundreds of thousands of microdrones. Sounds far fetched, but I think we will get there if the money tracks that is.

Imagine a puck of sorts, about the size of a dinner plate. Now imagine the same size plate about 18 inches above the other. Both plates could have a circular pattern of minute holes. One of the plates could pump out a thin haze and the other could capture it to be recirculated or vented out. A projector or series of projectors could create the "hologram".

Wonder if that would work?

I signed up and left a lengthy heartfelt comment. Any other plants on the back burner you can talk about?

I live in mountainous West Virginia and I remember finding chestnut trees deep in the mountains in the early 80s. I want some...I want to help too!

This person understands. I feel like people who say it wont change that much are either to young to have perspective o don't follow tech closely as I do. I have followed tech since I was a child in the 80s....its truly breathtaking to see what is happening now.

I was born in 1978 and what I have seen in my mere 40 some years would make your hair stand on end. Do you realize how much has changed in 100 years, which is the blink of an eye. I believe almost everything will be different 30 years from now. We can imagine this future easily because of how advanced we have become in the last 15-20 years. The last 20 years have been a real trip for me.

I believe tech like Neuralink will enable a type of digital telepathy. We will use actual speech less because we will be able to send it to one anothers brains. I believe the planet will heal due to tech like meat culturing. We wont have to keep concentration camps of animals either. This style of farming creates vast swaths of pollution...this will begin to go away. We will rely on things like insect protein...we will use it to print foods that mimic others so closely that you won't know it unless someone tells you. I am so excited for the future. I feel like we will think ourselves to a healthy planet...well at least a planet on the mend.

PS- we will be living on Mars by then and will be venturing into deep space. I think we will have known about ETS for decades by then too. Can someone remind me about this in 2050?
