Conspiracy about calculators

Phone calculators are absurdly weak. Like, mine blocks operations with numbers larger than 20 digits. Although it's obvious that even calculating a million digits is no problem at all. Why are they so limited? The only explanation is that a phone calculator couldn't possibly be a tool for serious calculations. It's like someone unscrewed their dick at birth and screwed it back onto the rest of their body only at 16. Now you have a normal task, download a normal calculator or use a computer. Why the fuck? Pure sabotage.
