Do you mean someone or some group of people is going to prevent the invention of this technology (individual self sufficiency) ?
Invention of technology doesn't rely on capitalist establishment though, as long as there is at least one engineer out there to work on it just for the sake of it. For example, the invention of linux.
No, but technology does not spontaneously occur. I am in fact a huge advocate of the development of liberatory technology like Linux, but I emphasize that actual people have to be working on that problem for the technology to develop. It is not the case that it simply “will happen”. It will only happen if we build it. The capitalists will not build it.
