This reaffirms the flawed notion IMO that the value of patents is in protecting ideas rather than the expense incurred in the development and validation of those ideas. A lot of the romance over patents is based on the idea of a lone inventor waking up one morning with an earth-shattering discovery, when the reality is that in most circumstances, those kinds of ideas are thought up by multiple people at roughly the same time, and rewarding the first person to write them down is counterproductive.

However, in the case of things like industrial patents or drug patents, where there is considerable cost in shepherding a design through a complicated regulatory framework, it makes sense to give the company that fronted those costs some kind of temporary protection from unfair competition. If you look at patents under that lens, it makes economic sense that an AI generating an algorithm over the course of hundreds of hours would be patent-worthy.
