alt Hacker NewsThey weren't torn down because there was better technology available. They were torn down because they were falling apart, or were no longer meeting the needs in that location. I love old buildings – my house is 250 years old – but there's no denying that generally they are less suited to current needs than newer buildings.
Older buildings are generally more flexible though.
In the UK, within living memory electricity has become widely available, TV has, gas, internet etc etc. and yet we still build houses without the assumption that some cable isn't going to be modified in the wall some how.
There's fairly modern houses that didnt have the 2 courses of brick added to the loft to allow 300mm of insulation to be installed.
We are now building houses with gas boilers, knowing that they will have to be swapped out probably before the life of the boiler runs out. And I bet the radiators and piping aren't sized to make that possible. That the circuit isn't sized for that.
Yes none of this is easier in a 250 year old house, but it isn't harder and 250 year old houses hadn't really changed appreciably for a few centuries so it isn't as if there would be an expectation that you would be installing new things in the wall every decade.
