Of course I do, but ChatGPT still has a free option. And the basis to compare paid subscriptions when there is also a free option stand IMO.
Without a good free option, how would it be only 5% who pay? It's exactly the same as with Youtube in that regard.
The free option is a form of advertising and allowing people to get to know the service. With Youtube the free option isn't really free, you pay by allowing advertising.
So by that comparison Youtube is actually the worse free option of the two. And despite that more people pay for ChatGPT.
So your argument that they are not the same, actually makes ChatGPT numbers even more impressive not less.
WTF?
The article even state this fact as a barrier to attract scientists to Europe from USA.
But here you go:

Everybody who has followed this issue even superficially knows this!!
Universities in USA also pay more, because they are very commercially oriented, and American universities compete on prestige, and they have more money than other universities around the world.
Try to look it up, and find info to the contrary if you don't believe it. This is freaking common knowledge!
