Is it possible to implement a time capsule in software? For example, somehow (cryptographically?) enforce that the contents of the software are not readable until a date in the future?

You're looking for "time lock encryption". Gwern [1] is a reasonable place to start. Or re Bitcoin [2]. But as these state, the risk is your specific implementation tech breaks in the intervening decades.
