If you're not testing your code under extreme latency it will almost certainly fail in all kinds of hilarious ways.

I spend a lot of time with 4G as my only internet connection. It makes me feel that most software is quickly produced, poorly tested, and thrown out the door on a whim.

That would be an accurate summary of almost all software.

Either it's quickly produced and thrown out the door as it's a startup trying to iterate and find market fit asap or because it's a bigcorp who's metrics are all not related to software.
