Numerous things will be explored in "the machine shop". While digital tech is all about software, this is where we deal with hardware. Opening up computers, laptops, tablets, phones and dealing with the complicated mess inside. But also installation of appliances, electrical wiring, data connections, cameras, security systems, Wi-Fi networks, and other things. 3D printing is on the table, but as that needs significantly more development before practical implementations become possible, it will likely be more than a decade before this website will receive any updates on that. Nonetheless, there is great potential.
At the machine shop, we also find out how to build things independently from scratch. The global village construction kit as seen on Open Source Ecology is interesting. Never mind the name, that's likely a lure or marketing—it seems like the guy is just trying his best because it is his passion and livelihood. What's important is that there is a very practical aspect to the project. And the documentation available for the GVCS is noteworthy. Check Marcin's latest blog post (at the time of publishing this). While it will likely be many years before this type of development and production could be popularized, if ever, it is a seriously good effort, especially at this stage of human development.
As for the remote control toy car talked about at the bottom of this website? That was a lie. Maybe it won't be towards the end of this decade. Meanwhile, here's a video of Marcin explaining his vision for Open Source Ecology:
