While the waste is lamentable, perhaps it's also worth considering this as a UI/UX problem. How many people mis-read the paper test vs how much extra error % does the circuitry introduce?

Would it be possible to make a paper one have words (such as pregnant/not pregnant) instead of one/two lines?

I'm not too sure why this is supposed to be surprising. When chemical reactions are involved, you often need chemicals.

A significant portion of digital meters used for servicing swimming pools require servicing/replacement of strips/chemicals (reagents) within the device.

Yes, there are also digital meters that work without chemicals per se, and have special electrodes that measure electric current. However, this approach quite simply doesn't work for all chemical reactions.

Have an app that uses the phone camera?

It's surprising because the electronics are essentially useless. Most people would expect the electronic version would have some type of advantage, because those electronics cost extra money to produce.

My 3rd world country has pregnancy tests[1] available in almost all vending machines, but unfortunately they're the paper kind. Obviously we managed to get them evenly distributed, but utterly failed to provide the future.

[1] For the convenience of both those hoping for positive results and those hoping for negative. I'm guessing there are more of the latter than the former, because they're invariably located in the slot next to the condoms.
