"This one might be a bit obscure just because I've only ever met one other person familiar with it, but Google's Project Ara modular smartphone was looking like it could've been the end all be all of smartphones.
Based off the Phonebloks idea of having a Lego-like hot-swappable module phone, the idea was that you could switch out any components of the phone on the fly. Camera, fingerprint scanner, even different quality screens. Conceptually, it really looked like it could take over the phone market, as it would lead to people not having to buy whole new phones anymore, but rather replacement or upgraded parts to a phone they already liked, thereby reducing costs and increasing utility.
You don't want a phone with 5 cameras that inflate the cost unnecessarily? Just buy a one camera module. You want a 1440P Super Amoled screen to replace your 720P regular screen? Buy one and swap it in.
However, like many Google projects, it died off for myriad reasons and the longstanding era of $1000 dollar smartphone slabs lived on."
Wrong on all counts.
