> The need for water per individual hasn't changed much in 80 years? 100years? more?
Unlikely. 100 years ago we didn't have nearly as much water infrastructure and appliances. It's difficult to find data on past years though but when looking at other countries that have less amenities than the United States the water usage is staggeringly different [1].
I would be shocked if, per person, the water usage hasn't gone up by double since 1915. Don't forget the infrastructure also has to handle a far denser population as well.
> The need for electricity has gone up a little since say 1940.
Define little. Almost everything we do today involves electricity whereas in the 1940s that was far from true plus the population has grown significantly since then. WorldBank seems to indicate it's been increasing (they have data since 1989) [2].
> Natural gas, and other utilities. Maybe even streets also seem relatively static?
Are you sure? Where are you getting this data? According to the EIA[3] natural gas usage has gone up about 5x since 1949.
> Getting public tech services upgraded at or near the speed that tech accelerates seems highly unlikely. Having public wifi would seem like it would remove a huge incentive for anyone to come in and offer better faster service because competing with free will be hard for a very very long time.
While I agree with you there is also a huge burden on getting around publicly allowed monopolies for the last mile (since the wifi needs some sort of data connection) so I'm not convinced any private companies are going to do this anyway due to that unless the government is going to offer some serious incentives or someone invents a better wireless technology which doesn't require a physical internet connection to the access point.

- yonran 11y agoI believe your parent post was referring to household usage (which determines infrastructure needs in a city), while you are referring to economy-wide usage. Energy usage per household seems to be essentially flat for the past 40 years according to Residential Energy Consumption Survey[1]. As for water, I can’t find any links at the moment, but I would guess that per capita indoor residential water use is also flat or slowly declining as appliances become more efficient.

- BinaryIdiot 11y agoPer household is kinda irrelevant for his point, is it not? You need the additional infrastructure to handle a more dense population and his point was regarding the upgrading of utilities.
