The assistants today are nothing more than just toys. They feel unnatural and have lots of problems when it comes to understanding context, sloppy language, and various accents. Siri in my case has problems with my ts and ds, because I speak English as a second language, so she mixes up "thumb" and "dumb".
However, I could really see them in the future playing a huge role in the house especially when we start integrating IoT enabled devices with them. Imagine the following dialogue:
- Hey Siri, I think I'm going to have fried eggs and a salad for breakfast tomorrow.
- What do I need to get from the store?
- Hey N. You need to get eggs and tomatoes for the salad.
- Excellent Siri, remind me to do that 45 minutes before leaving work.
.... (45 minutes before leaving from work)
- Hey N, don't forget to pass by the store and get eggs and tomatoes for the breakfast tomorrow.
.... (on coming home)
- Hey Norm, did you get the groceries for tomorrow's breakfast?
- Nah Siri, I forgot.
- Okay Norm, should I remind you tomorrow?
- Nah Siri, it's fine.
Today this dialogue is kinda possible but not really. And this is what I want. Just a helpful voice around the house that could help me with old fashion house chores. What I don't really need or want is an assistant that can answer the question "Who is the Queen of England?"
p.s. You also mixed up Tesla's and Apple's primary goals when it comes to cars. Tesla wants to build an electric car for the 1st world, Apple wants to expand its eco-system to self-driving cars. My impression is that they're going for the augmented reality, where the AI is just a helpful hand rather than something that drives you everywhere while you read the news.
Tesla is not the biggest electric car manufacturer in the world, it's BYD. They are a Chinese company that produces li-ion batteries and electric cars for the Chinese market. Whether Tesla succeeds as a mainstream car manufacturer is a different question. I don't know. They've been pretty successful so far, but whether they are going to continue their success is a tough question to answer.
