I'm talking about stuff like battery preconditioning based on selected chargers and also charger-based route-finding on the internal infotainment. Tesla has been pretty good about updating their cars, but I could see features breaking on many models. Heck, many cars from mid 2010s and earlier have had all connectivity break a few years ago when the cell carriers shut down 3g networks.

Software support is going to be the main issue. Unlike an ICEV, software does need to be updated because most EVs use connected car features and software for DC fast charging. Your EV may work fine in 15 years, but it may not support certain DC fast chargers.

Based on what? Motors often last 20 years despite typical warranties in the 5-7 year range.

I recently saw a 20 year old Rav4 EV listed for sale that was fully working. There are original Tesla Roadsters coming up on that milestone (though those did have a replacement program in the mid 2010s).

Most of them are safer than new due to better avionics (things like GPS, storm scopes, etc.). The only things that typically haven't been redone are airframes, which are inspected on a regular basis.

A huge portion Cessnas in the sky today (probably the majority) are 40 years old or more. Keep in mind that they have basically been completely rebuilt several times over by that age.

Any large organization imaginable has practices that depart from theoretically most efficient.

In the case of the government, it's often bound by legacy issues worse than any for-profit company coupled with legal issues that no for-profit company is subject. For example, the IRS is behind on tech in large part because its code base dates back to the 1970s (and contrary to Dodge, you can't just feed COBOL into AI and magically bring it up to date), and also because many of the notice requirements that require paper mailing are required by Congress. Many of the fixes you'd want to do in a private organization require an act of Congress, which may be impossible to get support to.

But the problem is that there is no free lunch with government budgets. Saving the REAL money involves tough political choices. For example, the federal budget is dominated by the military and entitlements (social security, Medicare). Much of the military budget is benefits for servicepeople and veterans. But what politician is going to campaign on cutting VA benefits? What politician wants to announce Medicare cuts? None of them. So they go after silly stuff like USAID that's a rounding error on the overall budget.

It's keyed to revenue targets, so they don't get to choose when it hits.

I guess you didn't learn about "silent e" in first grade like my kids did from their public school teachers.

I'm not a supporter of Sanders' plan, but it's a one-time tax, so government ownership wouldn't become 100% under it.

I wasn't saying or implying that Harvard is the norm or really talking about Harvard specifically. I was just presenting extremes of the college experience. Those extreme's make the averages meaningless. It's like comparing my wealth to that of Elon Musk, the local car dealership owner who is worth $20 million, and saying that on average we have over $300 billion. Doesn't give you much meaningful information.

Your small private college wasn't really the norm either. Most college matriculants numerically are going to community college, local state schools, and for-profits. Non-profit privates (both elite and non-elite) are the minority.

I don't think TFA is saying that kids couldn't read a sentence out loud. They can "decode" words. The accusation is more about attention span and reading comprehension. It's a stretch to attribute that to lack of phonics instruction.

The use of averages to obscures huge differences within higher education. Harvard isn't going to bend over backwards to accommodate a horse because they don't have to (unless they think the parent is going to donate a full equestrian center). They don't have trouble filling their classes with full-pay students. By contrast, your local CC or directional state school isn't getting remotely like 40k for a student in revenue (let alone profit). It's students at the latter that disproportionally make up freshmen dropouts. At highly selective schools, graduation rates typically exceed 80%.

The unions are very regional and also aggressively gatekeep. A few years ago I had an interesting conversation with a plumber in NYC. He had been shut out of the union and barely met ends meet. Outside of the East Coast, most plumbers aren't unionized. What often happens around here is you have one licensed plumber and a bunch of low-wage assistants (usually barely above minimum wage) who do most of the worth. Similar issues with a lot of trades.

I think you've been sold a story by people with a political agenda (i.e. attacking teacher's unions and anything they think is "woke"- i.e. anything they disagree with). Public teacher's unions and schools aren't responsible for curriculum selection. That's done at the state and district level. And any teacher I've met would laugh in your face if you said they thought correct answers to math problems are "white supremacy."

There are good engineering reasons to avoid replaceable batteries. The strategy has been used with some limited success in China, but charging advances are limiting the utility. They are rolling out EVs that can accept charges at 1MW, which means full charges in under 10 minutes. It does require building out those chargers (which use a large battery to discharge rather than attempting to generate that sort of power directly from the grid), but it's less intensive a lift than battery swap stations. The problem with swap stations is they are by necessity make and model specific, while chargers can be universal.
