I found that there's a surprising difference in quality for what feels like it should be a commodity item. All the outlets in my newish build were tamper-resistant, and pretty much as you described -- at best they were unpleasantly stiff and awkward to use, and some specific outlets would require a worrying amount of force and wiggling to plug anything in.
After a couple of high-usage outlets got jammed to the point that nothing could be plugged in, I replaced them with ones from the hardware store, and they are a big improvement. The existing outlets are unbranded, and I guess were from a bulk box of the cheapest that the electrician could source.
In my experience, Leviton are OK (much better than what was originally fitted), but Eaton are great -- they require slightly more force than non-TR outlets, but they're consistent, reliable, and I've never had to try more than once to plug anything in.
This is not a dissimilar system to Teletext[1], which transmitted data in the blanking interval of a broadcast TV signal, and could be interpreted by a TV or other hardware with appropriate support. Teletext was pretty widespread throughout Europe in the 1980s and 1990s.
It was typically used to transmit pages of information (news, weather, etc.) that could be viewed directly on the TV, but the BBC's Ceefax[2] Teletext service was also used to distribute software to the BBC Micro, when equipped with the appropriate Teletext Adapter[3].
In a similar fashion to the Sega Channel system, the Teletext system would broadcast looped data, with popular pages (such as news and weather) being repeated frequently so they would load quickly, and less popular pages taking longer to load (or more accurately, to wait for the next time they appeared in the looped data).
I was interested to see that the Sega system used a bitrate of 8Mbps, which sounded pretty high for the mid-90s, but I see that Teletext had a bitrate of almost 7Mbps for PAL broadcasts, despite being roughly 15 years older!
I can't speak to the cloud provider support, as I don't use it, but they have supported scheduled backups since at least June 2019, as I have locally-stored backups from scheduled Takeout jobs going back that far.
Bear in mind that the scheduling support is extremely basic -- the only option available is to schedule six exports, one every two months. You can't change the frequency or the number.
Also, you can't pick when the schedule starts, so if you want backups every two months indefinitely, you have to remember to schedule the next set of backups two months after the final backup of the previous scheduled job finished.
There were also several others, including some live shows, all of which can be found on the BBC's Computer Literacy Project Archive: https://clp.bbcrewind.co.uk/
I think the speed that things can go wrong when using a table saw (or most power tools) is faster than some people, including some woodworkers, might expect. There's a good example video here (warning, shows a very minor injury):
While we're still not talking microseconds, I think it highlights that moving the blade out of the way needs to happen very quickly in some cases to avoid serious injury.
