Have you heard of rewind.ai? It does exactly that but for your computer screen. I find it incredibly useful. Combined with this, the future looks very promising!
This seems seriously cool. I wonder if its constant recording is going to fill up my HDD.
edit: found the storage option. It defaults to keeping all data, but I've changed that to one month retention -- they say they use around 14GB a month.
It reminds me of having to use screen recording software for a previous remote job. I wished I could use that recording to do something exactly like this. Now, if only one could flip the script, and make the employer request that recording, instead of forcing one to share it.
