AI is a meme and the desire to attribute sentiance to it is just techie autism.
Consider the following, is, according to your three traits, a kettle sentient?
>Observe
Yes, it has a bi-metal plate to sense heat
>React
Yes, the bi-metal plate bends and thus powers off the kettle at the right temperature
>Goal
To boil water
If we follow this line of logic, we see that by your description, basic automation = sentience. At the end of the day even the most advanced "AI" is just a kettle, only with hundreds of times more sensory organs and internal logic calculators instead of a singular bi-metal plate.
