Some art is treated like an investment, it is speculated that the price of a piece is only going to go upwards. That is a reasonable assumption if the artist is famous, especially if the piece of art reflects a certain style or creative period. Usually it is very hard to copy the work/style of an artist. That said, I don't know how these pictures are going to hold to that assumption, since 'generative art' is by default reproductible and should be easy to copy...

Some people actually like having multi million dollar paintings hanging up. But, the number of people that can afford to do so is relatively limited.

Some as you say is pure speculation, but money laundering is also a significant part of the art world. Auctions regularly move vast sums of money between near anonymous people and represent highly portable wealth.
