At a glanceSamsung described a research prototype developed with the Bill & Melinda Gates Foundation. A working prototype and a mass-market toilet are different stages of development.
Who worked on the project
Samsung announced in August 2022 that its Advanced Institute of Technology had completed core development work for a prototype responding to the Reinvent the Toilet Challenge. It said its collaboration with the Bill & Melinda Gates Foundation began in 2019 and included prototype development and testing.
The foundation partnership is more precise than a headline suggesting that Bill Gates personally designed a Samsung consumer appliance. The named research organization, the challenge and the stage of development explain what was actually being announced.
Source [1]Why the word prototype matters
A prototype gives engineers something they can build, operate and test against a design objective. It does not, by itself, establish a retail launch date, the capacity to manufacture at scale, or the cost of installing and maintaining the device in different communities.
For sanitation projects, the setting is part of the question. A household, a dense urban neighborhood and an area with limited infrastructure can have very different operating constraints. A useful reading of the announcement therefore starts with its stated development milestone rather than assuming one demonstration answers every deployment question.

Look for the next concrete stage: an independently described field trial, a manufacturing agreement, an identified operator or an actual product specification. Those would each answer a different question from 'can a research team demonstrate the technology?'
NewsCubby's Science section provides newer research coverage, while its Technology section follows product and platform announcements. Separating those two kinds of story makes it easier to judge whether a promising idea has become a usable product.
