Meant by who? Were the people footing the bill aware of this? People can like and do a lot of things. When money enters the picture it gets more complicated because usually the people who pay do that because they derive some gains from it. Historically scientists and mathematicians were employed by various patrons, sometimes doing astronomical calculations for horoscopes, Easter calendars and whatnot. Pure for-fun math was usually done by already wealthy individuals and not salaried employees like today. So it's fine that mathematicians feel this or that is their purpose, but they are coming to us asking for tax money, and so there is a bit of burden on them to be convincing. Before AI they used to argue how it helps physics, engineering technology, computer tech, optimizing logistics and telecom, cancer cures etc. Now the tune changed and it's retroactively now obviously just pure recreation and spiritual elegance. I also like math don't get me wrong. I think it's a great intellectual pursuit. But it's arrogant to expect that the money can flow by default.
