all computers should be like the one in star trek TNG, for simple feedback it just beeps and bloops in ways that are intuitive, and if it actually needs to use speech to relay detailed information it does so in a short and efficient message delivered in a clearly roboticly neutral yet pleasant voice.
speak for yourself, i just use a notification pinning app for my shopping lists!
Literally all it does it let me enter text, set an optional snooze timespan, and then it creates a persistent notification with that text which can either be dismissed for the specified timespan or deleted.
Super convenient and minimal.
