Besides being generally nice, it's also a total godsend when you have other things going on - I'm currently working towards a CS degree and there's no way I could've balanced the two if I had a "regular" job.
We're one of the few industries where we are not only able to work like this, but also have the tools to do it efficiently (because we built them!). Yet, inexplicably, the majority of companies still insist on cubicles, strict working times and constant synchronous communication.
To be clear, there are definitely disadvantages to this and we need to be very careful to not let this idea turn into a gig economy type situation where if the company doesn't have work for us, we don't get paid (stable pay is often far more important than how high it is), where an individual's slice is too small to live off of and where people turn into expendable "work processors", but if done correctly, this really does seem like the way forward.
