So you're telling me that a vaccine for a sickness with basically 1 year R&D to production turnaround time doesn't cause you to think twice, when a regular prescription can have side effects and need to be changed?
Think of any experience you've had with anti depressants or reoccurring drug as a prescription: it's frequent that people have these changed out because of the adverse side effects or lack of effectiveness. The joke used to be that a commercial for medication would quickly read out side effects on TV for 20 seconds straight.
What I'm saying is the complete lack of any critical thinking before taking the vaccine is disturbing.
That's not true. We used to collect client and server data both to detect issues and even if it was only in a subset of customers there is just some customer facing QoS issues you wouldn't find unless you were collecting data, that wouldn't be found on server side for example. Like let's say iPhones make an update and you're doing video streaming, maybe certain video formats would lag when streaming to the player but not on an android or vice versa.
