This wear is due to over pronation of your foot. Pronation happens naturally to absorb impact of walking, your foot ‘rolls’ slightly from the outside to the inside.

It’s quite a common thing for runners to have to deal with, obviously if you’re running you’re doing more footsteps and putting more stress on your feet, it can lead to leg hip and back pains etc if not dealt with. I have a slight over pronation and use structured running shoes to correct, but don’t need anything for my ‘normal’ footwear.

Your picture suggests you’re pronating more than you should, I see from another comment you’ve made an appointment to get it looked at which is good. The likely outcome is you’ll need structured insoles to help make your foot movement more neutral.

Risk, reward, consequence… your reward is you get to your destination a few milliseconds quicker. The risk is unpredictable behaviour from the other party resulting in a crash. The consequence is a potentially hefty repair bill, injury; and being very late to your destination.

Don’t just assume. Always better to be absolutely sure before you make a manoeuvre, it’s just not worth the risk.

“Exceeding expectations” concerns me when it comes from an engineer; they’ve spent a bizillion man hours working out every detail, checking and rechecking.

It shouldn’t be exceeding expectations if it was going well, it should be going exactly as expected.

It costs billions, and takes years to bring up the sort of manufacturing plant and infrastructure needed to produce silicon. It is happening, but the investment and expertise needed to do it means it’s limited to a handful of countries that are realistically capable of doing it. There’s also a huge risk of he investment not paying off in doing this too, most of the worlds high tech manufacturing is based in the Far East too, plonking a silicon fab in somewhere like North America makes it more expensive due to labour rates and the cost of shipping chips to the point they’re assembled into pcbs

If it were dark during the day you’d see stars yes.

What we see at night does change, you’ll see the constellations move across the sky as the night progresses. And this will change slightly over days and weeks as the earth wobbles on its axis, but essentially we’re going round the sun in one plane of rotation, and the stars are really really far away so their motion makes no difference to the position we see them in.
