You're right! And cars when they were invented didn't give increased mobility to millions of people, because they came from just a few manufacturers.
Cell phones made communication easier for exactly zero people even though billions have been sold. Why? Because they come from just a few different companies.
cars, up to relatively recently, have been pure hardware machines that when a consumer buys, they can own. Now that's starting to change. Let's see how "democratized" cars are when the manufacturers can hard-lock "owners" from them.
Similar story to cell phones.
LLMs are in this state right out the gate.
Cars are a great analogy because they made mobility significantly worse for people who can’t afford them or refuse to use them for ethical reasons.
