The way we deliver education, medicine and welfare changed more in a week than it had in decades.

As the coronavirus weeks turn into months, the way we work, communicate, date and are entertained will continue to change. Some concepts will be fleeting - Houseparty App I'm looking at you - while some new technologies will become so commonplace we'll forget how we went without them. Many will be positive, but it pays not to ignore the potential for harm.

My family, friends and colleagues became apt at catching up over video chats this week.

One-on-one chats were on Facebook Messenger, allowing mum to witness my eye-rolling response to her frustration over the closure of her local golf course.

Work meetings remained on Google Hangouts, where we mastered the online art of waiting for one another to speak, mostly avoiding a chorus of "sorry, you go".

Group catch ups, always noisy, often naughty and occasionally in varying degrees of intoxication, migrated to Zoom.

It's not immediately clear why Zoom seems better than other video conferencing options, but it does.

As a boarding school teacher now working from home, my sister is enjoying the "mute all" function.

My three-year-old niece came close to an introduction to "mute presenter" when she showed six of us around her backyard in Melbourne this week.

Despite varying degrees of separation across Australia and across continents, my family had never met over video chat before Tuesday.

Sure a mobile had been passed from drunken aunt to uncle down the table when we'd missed Christmas, but this was different.

"My social life has boomed since my self-isolation," a friend in Newcastle told me and her brother at home in Yeppoon on Wednesday night.

Scheduling hour-long video calls with people around the world has fast become respite from what seems like constant televised state and federal coronavirus updates.

My friends with kids have found vicarious video-chat joy watching their little ones have virtual play dates with little mates across the city.

A colleague said she'd asked if her two had previously been deprived socially, after watching them run around the house to find puzzles, books and toys to present to the screen to show their kinder friends during a video call.

I even signed up for two weeks of living room "movements classes" delivered over Zoom earlier in the week. I went once.

But with Zoom's corporate clients up 61 per cent on this time last year, concerns have rightly been raised over what it does with all those people's data.

Last Friday, Zoom issued a statement apologising for sending users' personal information, including their location to Facebook.

Even people without a Facebook account were having their data sold to ad companies, despite the company failing to mention this in its privacy policy.

While Zoom developers now claim to have amended this function, it probably would've gone unchecked had it not been for an analysis by Vice reporters.

In conclusion, while we stay indoors to stay safe for the next foreseeable future, it's worth considering what we're inadvertently putting out there which could cause us harm.
