Nerds don't just want to teach people to swim. They want to teach them about hydrogen bonds and the mineral contents of the water, the processes of water treatment, and the technical requirements for a functional pool.
Nerds don't just want to teach people to drive. They want to teach them about the engine, the drive train, the underlying transportation infrastructure, and how to change their own oil and tires.
If you want people to swim or drive or use the fediverse you skip all that shit. Normal people do not care.
Stop being nerds.
