>Our type of society is probably much much rarer because you need access to mineral and energy deposits to go through each technological phase. For example, because of all the mining we’ve done, if humanity were to disappear it’s highly likely the Earth would not sustain another technological society because all the “easy to get to” deposits of crucial metals & things like oil are gone and there’s no way to bootstrap a technological society (it’s possible other kinds of resources could be developed to build other kinds of technology so who knows).

As I recall-though it's been many years-this was something of a premise in Farmer's Riverworld series. Once you've taken the first pass though historical mineral etc. resources, you don't really get a second pass.

Readily obtainable hydrocarbons are lost for the forseeable future. However, haven't we made it easier for future civilizations to obtain minerals and metals? We have extracted, refined and placed them all in concentrated surface areas all over the planet (i.e. city limits)

Except a huge amount of it is alloys. You’d have to reprocess it to extract out the raw materials which is much harder than mining ore and requires a lot more tech. Like things may be bronze plated but you’re not going to find a whole lot of bronze in 1 spot.

Wouldn't the next civilization just find itself mining the remains of human cities? IIRC, the majority of the copper ever extracted is still in use.

Cue Indiana Jones voice: you can’t just mine that—it belongs in a museum!
