Jobs' Mob's poor design decision to hide the comma and full stop behind a symbol switch has made it too hard to use puntionctuation and capitalisation.  

"By hiding the comma and period behind a symbol switch, the iPhone keyboard encourages the biggest grammar fiends to be lazy and skip punctuation," writes El Khoury.

El Khoury highlights the cumbersome nature of the iPhone's keyboard layout.

"Pundits will say that it's just an extra tap to add a period (double-tap the space bar) or a comma (switch to the characters layout and tap comma), but it's one extra tap too many. When you're firing off replies and messages at a rapid rate, the jarring pause while the keyboard switches to symbols and then switches back to letters is just too annoying, especially if you're doing it multiple times in one message. I hate pausing mid-sentence so much that I will sacrifice a comma at the altar of speed."

The core issue, according to El Khoury, is the overwhelming popularity of iPhones among Gen Z buyers, particularly in the US, a market with significant online presence and influence.

Most smartphone users tend to stick to default apps on their phones, leading many to use the iPhone's default keyboard instead of exploring better, albeit often slower, alternatives.

 "And it's that same keyboard that's encouraging them to be lazy instead of making it easier to add punctuation."

El Khoury states, "So yes, I blame the iPhone for killing the period and slaughtering the comma, and I think both of those are great offenders in the death of the capital letter. But trends are cyclical, and if the cassette player can make a comeback, so can the comma. Who knows, maybe in a year or two, writing like a five-year-old will be passé too, and it'll be trendy to use proper grammar again."
