Nothing exploded while most companies had no idea whatsoever on how to implement it properly. Things worked mostly fine even though it was through a panic emergency plan that was completely winged due to sheer necessity.

Imagine if it was a plan properly designed and implemented? All this bullshit of RTO is getting old for me exactly because of this point, nothing was done in what would be even close to the optimal way for working remotely and things are still going ok...
