(Sharing because I've been trying to do my personal learning on this topic)
It's been a rather contentious topic, and sciam has even written about some of the issues: https://www.scientificamerican.com/article/evidence-undermin... ( https://archive.ph/N1nAR )
"The American Psychological Association and 61 other health care providers’ organizations signed a letter in 2021 denouncing the validity of rapid-onset gender dysphoria (ROGD) as a clinical diagnosis" -> https://www.caaps.co/rogd-statement
There were protests around this back in 2022. See https://moneyontheleft.org/2022/07/16/bitcoin-in-el-salvador...

Personally, I just got afraid of ever buying takeout sushi, put a label on the black spatula and hope to use it for garage experiments but you do you...
> "This blog was sponsored by ZIRP. The future historians who dive into these archives for archaeological research will likely be economic rather than cultural historians, trying to reconstruct the play-by-play impact of ZIRP. Many of the big hits of this blog, such as The Premium Mediocre Life of Maya Millennial, and The Locust Economy (a forgotten hit from 2013) had ZIRPy subtexts."
I think the author might he referring to their own blog (ribbonfarm) as a ZIRP phenomenon, not the whole blogosphere.
Neat to see someone attempting a cross-platform approach!

Possibly one change in 2024 is that Typefox (which contributes to Eclipse Theia) announced Open Collaboration tools: https://news.ycombinator.com/item?id=40970621 -> https://www.typefox.io/blog/open-collaboration-tools-announc... (2024)
There's another important county election in Sonoma happening about CAFOs where part of the issue is that you may get environmental progress locally, but just end up exporting the issue to another state with lax rules: https://www.kqed.org/news/12006460/the-sonoma-ballot-measure...

Another comparison might be a Jeep Wrangler base 4dr (4449 lbs curb weight and up) compared to the 4xe PHEV version (21 miles of ev range, 5,072 lbs curb weight and up). Roughly a 500lb weight increase.
You could try this comparison on 2wd vehicles as well if desired (e.g. toyota prius vs. prius prime).
While neither scenarios are an EREV, the comparison is a bit similar in thinking about the tradeoffs in hybrid conversions of existing ICE vehicles, where presumably the engine would be retained and drivetrain/battery components to facilitate electric propulsion are added.
Designing an EREV from ground up can be much less weight but depends on vehicle type size, such as a BMW I3 (a small urban 2WD car with CFRP body panels, narrower staggered wheels and other weight savings by design) has a curb weight closer to 3276 lbs. There's tradeoffs with that low weight - the small range extender engine has less power, the gas tank only adds about 80 miles of range, etc.
Weight: You're adding about 500 lbs to the car to do this with ~20 miles of ev range. Suspension may need to be altered to support this.
Practicality: the batteries have to go somewhere and they can't go under the hood since the engine is still there, so they may go in the bottom of the trunk. From the examples I've seen there's usually less cargo capacity, and the spare tire is removed. Some vehicles that are already hybrids (e.g. Toyota sienna 2022-) have an already tight layout with exhaust and all that it becomes a design challenge to fit a larger battery.
Thermals: a li-ion battery for an EREV likely needs thermal management so it doesn't lose range prematurely, so you either need a dedicated cooling line setup that works with the ac compressor (bmw i3) or an aircooled setup where the battery is in the trunk and relies on cabin ac/heat (various toyota hybrid models do this).
Thus you ended up with more SUVs, and by 2020 you had some automakers (e.g. Ford) stop selling cars altogether in the US market.

"The light truck standard was increased to 20.7 mpg in 1996, where it remained until 2005. NHTSA promulgated two sets of standards in the mid-2000s for MYs 2005-2007 and MYs 2008-2011, increasing the light truck standard to 24.0 mpg. In 2007, Congress enacted the Energy Independence and Security Act (P.L. 110-140), mandating a phase-in of higher CAFE standards reaching 35 mpg by 2020. This was the last legislation to set fuel economy goals"
The article doesn't quite mention it but back then the other option to get internet on a laptop was a dedicated USB dongle modem or Wifi hub thing.
Probably the next 'oh that's neat' moment happened a decade later when usb-c tethering became enabled such that one could tether a whole ethernet network of things to a phone if needed on occasion (e.g. broadband outages, moving to a new home)
Just adding some historical notes, Portalplayer's IC was used in the iPod until 2006ish ( https://en.m.wikipedia.org/wiki/PortalPlayer ), the first iphone used a Samsung ARM chip (https://en.m.wikipedia.org/wiki/IPhone_(1st_generation) ) , and fabless design companies like P.A. Semi and Intrinsity were acquired by Apple in 2008 and 2010, respectively.
Personally, I havent understood this design and think it may be better to reuse an old tablet if one really needs a second screen.
I'm not trying to take an endorsing position on e-fuels, but wanted to note Prometheus talked in one of their interviews and argued they would work around tensions with 'big oil' not via legislation but having direct customer relationships with competitive price commitments:
From interview of Rob McGinnis ( https://curiositypodcast.substack.com/p/future-of-sustainabl... ) of Prometheus Fuels:
"We have not gone to raise money from anybody in oil and gas. We've always said we wanted to go to our customers and form relations with them. So that's why a car company and a shipping company, for example. And we did LOIs with airlines. The ones that got published was with American Airlines. We said we'd give them 10 million gallons of jet fuel for one cent less than the spot price of Jet A."
