A lot of ADs sell these watches to people who can't afford them... There are people who buy Pateks solely to flip them for a profit. They can't really afford to hold onto them long-term as the funds are earmarked for investment, not enjoyment. There was a fella who was once trying to remodel his house, and the renovations cost a lot of money, he wanted to buy a Patek Philippe Nautilus and eventually sell it to pay the bills with the profits. True story! He couldn't afford it - not with the renovation. But who knows. Bard's overall not wrong with that statement, maybe there's some deeper reasoning it didn't want to explain. We humans make too many assumptions and presumptions, almost all the time unaware of it.
But yes, you're right, BARD is an "AI" it's not perfect. Of course it's going to give off the basic ideals and rationalities first. It's not exactly a super deep thinker yet. But for it to have mentioned training, I thought that was deeper than I expected. That shows BARD probably knows training exists, BARD identified a need for it, and BARD identified the positive value of its impact, and that impact was substantial enough that training would be a viable return on investment, and maybe more other parts of the logic chain were considered. It's something that many jewelry stores haven't considered in my opinion.
