You do realize they could be campaigning on these things. Making noise, drawing more attention to Trumps policy failures. Maybe it's just the reporting of it, but the only person I actively heard making a big stink within the party was David Hogg. The party had a big issue with his approach that they used a technicality to remove him from his position in the party.

The difference everyone always ignores is that most of Chinese infrastructure is new. For the US they’d need to buy people out of their land, build new tunnels and bridges, and disrupt so many things to implement high speed rail. You can’t just leverage the existing rail network because they have curves and grades that are incompatible with high speed rail (northeast corridor has 30-40mph limits on some curves). In addition you’re competing with airplanes which are already proven and support current travel demands. And even if you could get the rail implemented there isn’t any guarantee it’ll be any cheaper than flight (meaning low usage). As it stands today going from major hub on Amtrak can be more expensive and takes an equal amount of time (when accounting for security/etc.)

I feel like people forget how much infrastructure is required to keep high speed rail running. Not only do you need the stations, but the tracks (bridges, tunnels, etc.) all need to be maintained. Additionally, when doing maintenance you can’t run the line, so you either need extra capacity so you don’t disrupt service or you end up with times you have to shut lines down. In comparison, planes just need a strip of flat land at takeoff and landing (you technically don’t even need an airport). You’re primary bottleneck is how fast you can get planes on/off the tarmac. One of the other big issues in rail vs plane is that high speed rail only works at certain grade levels and turn radiuses. So for example, I believe you couldn’t convert the existing northeast corridor in the US to 300mph rail from end to end simply due to the geography. You’d need to create a new route. Looking it up there are speed limits around 30-40mph for Amtrak around Baltimore and Wilmington.

Or space! I feel like that's the reason people have been talking about space data centers. Once it's up there it's kinda hard to get access to it.

I thought the same, but they still make the 20 Oz bottles. Looks like the vending machine company is either cheating people or forgot to update the placards - https://www.target.com/p/pepsi-cola-soda-20-fl-oz-bottle/-/A-12979694

I think it’s a “dog whistle”

Yeah, people always seem to forget that it’s about what you can purchase, not the $ amount. Similar to living in a city vs a rural area, the cost of food/housing varies widely even in the same country.

I was going to ask how this is different than a Reinforcement Learning algorithm but then they called out Deep Minds Alpha-Go

Robotron 2084 - there is a place by me that still has the arcade cabinet.

Use Google Collab or another web hosted platform. If you’re unfamiliar Google Collab is a part of Google docs that you can run Jupyter Notebooks on (and it’s free). This avoids the need for anyone to install anything and means you can test materials in the same environment everyone will run against. Additionally, Jupyter notebooks makes it easy to add markdown, so instructions can be in stylized format and the students can run the cells over and over again to see how the output changes in real time. Lastly, I would lean towards python, but there are many different languages supported in Google Collab and similar web hosted tools.
