I remember growing up and in my home my family would frequently encounter the difficulties or annoyances of life and remark, "if only someone would invent a thing to". Sometimes we wished for straight up science fiction but most of the time we wished for things that, with some effort, could be made to happen.

Most people would say that the 80s and 90s were marked with the rapid introduction of computer technology. But I'd argue that it was also marked with total stagnation in just about every single already mature industry, particularly for end users.

I live in an urban environment and as such I am often walking, into and out of cars, buildings, etc and so I frequently listen to music on my headphones. I also travel work my work and some of those flights can be very long. As such I want to have noise cancellation to my headphones. I also want to increase the usability of my current headphones. The cord can be annoying but I also can't take calls on them or control music playback. I want all of this without compromising the fidelity of the playback. I want my cake and eat it too... but what does that look like?

Watches are jewelry and as a result there is a wide variation both in price and quality. I'd love to perform a study and scatter map price and quality. The most you could hope for is a straight line: higher price results in higher quality. But in reality I think what you'd end up with is a cloud with very little statistical correlation. Even if you were able to normalize for precious metals or technologies that lend themselves to aesthetics rather than robustness I don't think if would make much of a difference.

Some time ago I had some kind of error or corruption with my *Google Play Games* on my *Nvidia Shield TV* console. I am also a *Google Suite (GSuite)* subscriber which adds additional constraints. Any time I chose to log into google games the system would log in but then the game could not detect the log in. It was odd and I knew the issue was probably a local error. As it turns out there are a lot of hidden secrets that you need to check / setup before it all works. And any games you've played so far will probably lose their unsynced data.
