That said, my experience with LLMs is that they tend to lie/misrepresent user input and intention, especially when translating text. Doesn't sound like a problem to me if you're just ordering pizza or scheduling a haircut, but when it comes to healthcare, that might become problematic. Furthermore, there are quite a few regulations when it comes to healthcare services that you might need to double check, just to make sure you're avoiding having to comply with difficult and expensive regulation. Not really an issue for a tool built for your parents, but when you're marketing it to people (especially vulnerable groups, like people not speaking the language of the country they're in).
Also, does this bot announce that it's a bot?
Also, how will you prevent scam callcenters from ruining your bot's reputation? Is there some kind of abuse detection in place? Because if you just have a service that will call people and tell them what you instruct it to tell them, I can guarantee that malicious people will flock to it.
Because why would you want to make phone calls in the first place and not just send an email, or an SMS?
Because of spam filters and because people do not read their emails immediately because we get so many. But now we just get the same with phone calls.
It was already bad enough with fake Microsoft support.
Or, you skip all that and just put it all in an S&P 500 fund.
The bubble burst in 2000-2001, Google IPO was in 2004.
The S&P500 also did not do very well at the time.
That is the problem with bubbles.
