People thought we couldn't fly once, or go to the moon. And I tend to think that people won't be displaced from climbing trees.
But have you seen the number of robots used for havesting and manufacture.

1. Sonic device to perform sonar-like wood density tests.
2. xray device to detect cavities.
3. Laser cutting tool
4. Multiple mechanical arms for tools, rope and gear.
5. Cable and rope stored in spools for easy dispensing
In one way, it seems impossible, but considering the technology that's been accomplished lately, I can't say that it's impossible.
