I don't like ORMs, but Prisma is one of the better ones. It avoids a lot of shortcomings of popular ORMs. I hope they find a way to make it work as a company. I've been following them over the years from the beginning of their journey through various pivots.
To use an ORM effectively you must learn both the API of the ORM and SQL. It does not absolve you from learning SQL, which I think was one of the unstated attractions to junior developers. Then you have to map between the API of the ORM and how it translates that to SQL under the hood. Then you have to understand how it handles caching and sessions and how that all works under the hood. This has been the source of so much complexity and so many bugs over the years that I no longer think the benefits are worth the cost. As always, there are exceptions and caveats, but I now believe it's better to use SQL directly than to use an ORM. In general there is too much complexity in all the layers of abstraction in software development these days, and I think the industry is strangely blind to the consequences of this. Complexity is death to software, and it should not be taken on lightly. The entire craft of a software engineer boils down to eliminating complexity and simplifying problems, the better you can do that, the more productive an engineer you will be.[1]

It would contrast against traditional ("stateful") ORMs which use query builders (rather than raw SQL) to return database-aware (rather than pure) objects.
The name pureORM reflects both that it is pure "ORM" (there is no query builder dimension) as well as the purity of the mapped Objects.
