In-person and remote work usually have the same goal in mind: to get the job done. Of course, there are typically a lot of things involved with the "job" such as teaching new colleagues and collaborating. Not having the right tools and environment can make this harder. The "open office" is really more of a cheap way of setting up an office than one that is conducive to work or training as it is rare that everyone in speaking distance wants to hear an extended conversation about training or chatter about sports.
Collaboration and training takes interaction and that is something that needs to initiated on a regular, not necessarily scheduled, basis. Remote workers often need to be reminded or have a regular way of initiating conversations which is often overlooked versus a "watercooler" discussion.
Tools like Zoom make a big difference. Take it from someone who grew up with telephones and modems. Still, you need to remember to turn on your camera and keep your group interaction small if you are looking for one-on-one interactions. It is surprising these days the number of people that keep their camera off and their microphone muted when they don't have to. I am not talking about the large one-way training sessions but the more intimate discussions of two or so people. The excuses are numerous but like being in person but sitting on the other side of a cube's wall. Think etiquette.
I find a lot to agree with in your comment. I suggest those interested in a better C investigate Ada in addition to C++. It is amazing how many are trying to create a better C and overlook the fact that the alternatives already exist. They are just not as popular because "they are not new".
I also find it interesting that many of those involved in designing these new solutions have not done a better job of learning about these existing alternatives to understand the features and implications that they are trying to incorporate into their new language.
I also wonder about the many excuses for not using a particular language are common regardless of which you choose compared to your current one such as a different syntax, need to learn a whole new language, etc. The article, 11 Myths about Ada, highlights some of these issues with respect to Ada.
