A message or email works differently when you have an established relationship with the other party. It's one thing when I have to do something "because the company needs it" but totally different when I'm helping a flesh-and-blood coworker. You don't build relationships and trust through jira tickets and emails, you build them through unstructured messy human interactions. They pay off later.

Almost all the ones I've met.
Modern corporate environments are spread out all over the planet. If you can't build relationships without sharing air, you will be at a massive disadvantage. That's just how it is, and it isn't something that was caused by the pandemic, it's a consequence of intense globalization over the past ~40 years and an aggressive investor-driven acquisitions culture.
