well if you're assuming the same number of passengers - given the logistics and hassles of air travel, one is likely more inclined to travel with hassle-free HSR, not to mention the secondary economic benefits

This feels like its a semantic thing, really, its just a gate control of a certain access.

What? You opted for Spotify model when you sign up for the service. I am pretty sure you are still free to purchase the music or album in iTunes.

You’re even still free to just go buy the CD and rip it, as odd as it sounds.

What happens with your iTunes music if your apple account would get locked? Sadly the only option nowadays would be purchasing hard discs, and hope theres no protection on the disk as you are not allowed to break it

ITunes has been DRM free for over a decade?

Nothing, you can download all the music DRM free first. You do own what you bought, at least from iTunes you do.

When investors look to invest, they want a fast ROI. Engineering company likes this typically takes many years to fruition or maybe not. It's much easier to justify dumping money on these "tech" companies like WeWork, AirBnb hoping to get another facebook unicorn than putting money into real engineering company like Makani.

Personally I find that troubling for the progress of humanity. We need big money (resources) to solve real challenging engineering problems.

Unfortunately it seems like a lot of the big money is going towards less critical 'problems' if problems at all, like social media companies.

In my experience, it depends on which sport you do and when you do it during the day. I used to play squash during the evening around 8pm and on these days I would fall asleep very late, like around 2am. This was mostly due, I think, to my heart rate still being quite high (I could feel it), and slowing down very slowly until it reached a reasonable level at which I could get asleep. This is something that other friends playing squash in the evening reported as well.

Strength athlete here, I train in the evenings and my quality of sleep is always garbage when I'm peaking from all of the stress on my CNS. The end of cycles are hands down my worst sleep weeks, I'll be dog ass tired and have trouble staying asleep.

For one person a heavy day might be a few sets of deadlifts at 80-90% 1rm, for some of us that might mean 2-2.5 hours of training where are warm up alone moves considerably more mass than your entire training and then we also tack on multiple accessory movements and conditioning and if you aren't doing that in the morning it's almost certainly going to mess with your sleep quality that night.

I have a training-induced insomnia blog post that is years old and gets hits every single day without fail. It's probably 1/4 of the total traffic on my personal blog and probably more like 60-65% of Google-referred traffic despite the fact I have 18 years of blog posts.

I spent 30-45 minutes deadlifting yesterday and still had trouble falling asleep. It's not the perfect answer.

Problem is education. There is prolly literally little to none courses about computers in medical school in most part of the world.
