But, it can have electrical problems like too much capacitance in the wiring, inadequately sized pull-up resistors, a device connected to the bus that isn't using I2C signaling (e.g. The bus doesn't have state, so it can't crash.
I2C is a serial bus specification that uses open-drain signaling. Wire isn't supposed to reconnect to anything or do error recovery at the protocol layer-that's not part of its job. Wire function calls return error codes about things like whether there was a timeout (according to the I2C bus timing specs) or how many bytes were read from a slave device. It provides low level primitives for reading and writing on the I2C bus. Wire is the standard I2C library for Arduino, Photon, and maybe other similar platforms. Are you familiar with I2C, Wire, and writing Arduino firmware? From your description, I think you may have misconceptions about what I2C and Wire do and how they work.
