Why is a coworker referred to as 'they'? Is this a non binary individual or is this newspeak where normal pronoun of a known individual is replaced for some reason?
He didn't. His response is that the metric 'get as big tv as possible to a) fit 40% of your vision b) not waste money on the level of detail your eye won't perceive' is wrong.
Analogy - it's like saying that you should get a car that can accelerate 0-60 in 5s. Maybe you don't care about acceleration and prefer 10 cupholders.
If you are an entrepreneur reading this, IGNORE the comments. They are written by people who form a very specific (and small) subset of the overall market and have very little overlap with the actual world at large.
If you plan to sell to the HN crowd (let's say development tools or something nearby) - by all means listen to their views. If you do not - ignore all the 'i want free stuff' and focus on people who are ready to pay for whatever you are making.
It's fairly reasonable for someone who doesn't know the term 'arabic numbers' to assume that he's asked about style of number writing as currently practiced in the arabic countries.
"toy stores are deliberately and consciously avoided precisely because parents are annoyed at the effects"
This. I have a few kids of my own and make a point to never go with them to toy stores - they go crazy from looking at all the possible options and end up being unhappy because no matter what we end up buying, there is a gazillion things we ended up not getting.
Much better to get ideas from wherever (window shopping, other kids, forums, etc) and buy online - free no hassle / screaming delivery.
Even if you end up getting not the "perfect" toy they would have picked, it's a superior shopping experience for the adult.
"My family fled a decaying crime filled city to the suburbs."
Your family fled the huge crime wave committed by blacks in the cities in the 60s-70s. If blacks had not been brought over to the US in the first place, your family would not have to flee.
That's why it was called 'white flight' - it was whites fleeing rampant black crime.
