 Yet there is little question that remote work has real downsides.  Some of these, such as ensuring work-life balance, avoiding distractions and unhealthy at-home working conditions, are not easily addressed through remote collaboration tools.  But many others are: lack of organic interactions with colleagues, missing opportunities for feedback or to form deeper personal connections with colleagues, etc. [^remote-shift-impact] While ⿻ can be used to address most of these, we will focus on one in particular: the building of strong and deeply trusting teams.
 
-In-person teams often engage in a variety of joint learnings or other not-directly-productive activities to build team trust, connection and spirit.  These range from casual lunches to various kinds of extreme team sports, such as "trust falls", simulated military exercises, ropes courses, etc.  What nearly all these have in common is that they create a shared activity that benefits from and thus helps develop trust among members, in a similar manner to the way we discussed shared military service developing strong and lasting cooperative bonds in the "Post-Symbolic Communication" chapter.

 Obviously most such activities currently rely heavily on being in person, thus many hybrid and fully remote teams, especially those that have many members who started as remote employees, miss the team-building benefits created by such activities or can achieve them only at considerable travel expense.  Remote shared reality offers significant potential for overcoming this challenge.  Lunches among sufficiently realistic avatars, ones reflecting detailed facial expressions for example, may soon help bring the rich connections achieved in the office within the reach of remote teams.  While it would seem impossible to achieve the vivid connections of parties or extreme sports in remote shared reality, there is increasingly strong evidence that real experiences of fear and trust can develop in sufficiently realistic simulated environments.  As "e-sports" begin to rival the popularity and, in the right remote shared reality environments, physical intensity of in-person physical sports, the benefits of "campus athletics" may increasingly make their way to remote work.

+[^TrustFall]: A "trust fall" is an exercise where a person falls backward, counting on others to catch them. This activity is used to build trust and teamwork, as it requires relying on others to prevent injury. From the mid-2010s, the trust fall became less popular due to the potential for traumatic brain injuries if catchers fail.
