I think the lack of "getting stuff done" is due to the innovator's dilemma on a societal scale. The marginal gain of any additional project is just too small for society, as a whole, to care about.
Today, we have so much experience with building things, as if every invoice is ready to be sent to order every piece of a building, that we don’t have experience with repairing.
Moreover, insurances tell us that a desk or a telecom switch devaluates 25% per year, so we value the existing furnished building to basically scrap value after 5 years. But insurances evaluate at the resale price. But an equipment in-place and working has at least 90% of its purchase value for 3-10 years, if not 125% of its purchase value, since it would cost a lot of maintenance to scrap and re-plug a new one.
If insurances/accounting rules admitted that equipments are worth 90% of their purchase price for 3 years, we would put more value into repairing things. Our replacement culture is rooted in the way we perform accounting.
I've given serious thought to not having internet at home, because I grew up and spent nearly half my adult life without it, and it sure sure seems that I got more done in those days.
I don't think people quite understand all the fifth oder effects and dependencies that are at best ignored, at worst totally unknown.
