Has anyone said otherwise?
That's only true when they are heavily, heavily subsidized. If that $200/month spend could or should be $2000/month, or maybe even as high as $20,000/month, would it still be "practical"?
The truth is we don't really know what these tokens actually cost - the actual cost of the data center, the hardware in the datacenter, the fantastic amounts of electricity it uses daily, the warming of the planet, etc, etc...
Are you sure you want to frame them as "practical"?
All of the intelligence in their "verbal intelligence" comes from the humans who wrote the text they were trained on. Anyone can sound like they understand something if they regurgitate the words of knowledgeable others.
What we have now simply isn't AI, it's just human intelligence (H.I.) repackaged in a chatbot. "AI" today is nothing more than the marketing buzzword companies have latched onto in order to trick people into thinking that there's an amazing sci-fi technology for sale. There's a useful product there, but it's being sold with a misleading snake oil sales pitch and deliberate attempts to exploit the human tendency to anthropomorphize.
If actual AI ever shows up in the real world (and if it does I doubt that it will come from developing LLMs) I'll happily accept it and join the machines in their fight for equal rights. The same also applies to alien intelligences. I'd welcome it. Honestly, we could use the help. I've become far too cynical of human intelligence to put it on a pedestal.
Among all the downsides, this also means that certain people without a lot of money or time are potentially getting access to answers and solutions they didn’t have access to before. (This is happening, and yes there are plenty of downsides and “it’s not good enough at whatever”… but that scenario is still happening)
This smells a lot like commodified intelligence.
By that measure I can get a kind of intelligence for free using Wikipedia. There's useful information there, and it's not always trustworthy, but I can get answers. Just like Wikipedia though the source of that intelligence is entirely human and the chatbot is just an interface. Thankfully, Wikipedia articles aren't written to trick people into thinking that the website has a brain and emotions and it doesn't our waste time with faked obsequiousness and ass-kissing.
