This is one guy's opinion, not data

Good job proving you didn’t watch it, since the guy’s a trained engineer and his whole schtick is that everything he posts is data-driven. The first half of this video painstakingly lays out the data and methodology. But I know thinking is too hard and too woke for MAGATs.

I watched the video the week it was released, dipshit; I'm also about as far left as it gets so right off the bat you've made 2 erroneous assumptions. Let's go over the video: - Multiple times he says "I'm using the assumption that...". Assumptions aren't data. Sense a pattern here? 1/

- Not once does he mention cost to build the system out, nor a ticket price point which would make enough travelers ditch auto or air, nor the number of expected travelers at that price point, all three of which are needed in order green light the project 2/

- An inherent problem with a system like this is you need to either factor in cost to prevent terrorist attacks, or leave it out and wait for an attack to happen. Both approaches leave out cost estimates. Another omitted data point 3/

- I've been a software engineer for the past 40 years with the last 10 years focusing on data engineering so I'm pretty sure I have some expertise on the topic of data, but feel free to make some more assumptions as counter arguments

As if being a software engineer specializing in data science makes you an expert on intracity transportation. Me too am data science programmer, and thus me knows when to defer to expertise. You sound like a tech bro who thinks that being an expert in one field makes you an expert on everything.

It doesn't. I don't have to have played in the NFL to know when a quarterback makes a shitty pass. It's funny how factoring in cost has absolutely no meaning to you regarding whether or not HSR is feasible 🤦‍♂️

Another word for “assumption” is “hypothesis”. There is no progress without assumptions as a starting point. If you’re truly a data science engineer, you should absolutely know this. Calls your bona fides into question.

Ok, you just outed yourself, "assumption" and "hypothesis" are 2 completely different meaning words. Hypotheses are testable; assumptions are not

Dismissing a hypothesis because it’s a hypothesis is intellectually dishonest. The real question is whether the hypothesis is reasonable. CityNerd took great pains grounding his hypothesis in observed reality, notably in Spain. It’s lazy to just dismiss that outright.
