I beg to differ. Currency, weaponry, and agriculture are all technologies.
That said, my point is to not excuse technology. Currency and agriculture were both technical solutions to problems of poverty and starvation and I don't see a reason to exclude it from taking responsibility now.

One could easily solve the problems you mentioned if you had abundant cheap energy and millions of cheap robots that efficiently distribute food/goods on the planet. A system that could keep track of resources of the planet and efficiently provide a minimum level of food, shelter, safety for everyone. There’d still be the gradient of “if you work hard and create value for others, you get to keep your gains”. However the taxes paid would create a minimum bar of opportunity access for everyone.
One could say that what we need is a resource driven economy instead of a simple capitalistic economy that yields to monopolies and too much power in few hands.
To a large extent so is suffering, deadly pollution, insanitary living conditions, and underfunded schools and healthcare.
So pretty much everyone is not working on these problems in a capacity that matters. If you want to be, you need to be in the realm of politics, not technology.
