In the vein of "public libraries could never be created today," a pitch for a calculator would get you thrown out of the boardroom.
What do you mean, it just maths? Where are the ads supposed to go? How does it send usage telemetry back if it doesn't even have wifi? There isn't even a leaderboard.
Another massive difference is that a calculator isn’t answering your questions in a way that’s specifically designed to get you to continue using the calculator.
