Why do people buy NFTs?

Can you tell me, why is it that people are investing in Non-Fungible Tokens, or NFTs? What kind of value do they see in these digital assets that aren't interchangeable or divisible like traditional cryptocurrencies? Is it the uniqueness, the artistic merit, or the potential for resale that's driving the market? Or is there some other reason altogether? I'd love to understand the mindset behind these purchases and how people are making decisions in this new and emerging field.
