Now that most people have a fast internet connection

In the case of BitTorrent, even the fastest Internet connection won't get you a lot of successful peer connections if your ISP blocks all inbound TCP connections.

If youtube goes away, streaming video won't disappear, some new ecosystem will grow in its place.

Such a new ecosystem already has grown, as I understand it. It's called getting Netflix, HBO Max, Paramount+, Disney+/Hulu, Peacock, Prime Video, or Apple TV to accept your pitch and fund it. These take the place of cable television channels in the pre-broadband economy. And there are still a lot more pilot screenplays than budget to produce all of them.

You are speaking irrelevant nonsense. LLMs are trained in words

They are not. They are trained in tokens. Tokens do not align with word boundaries, and an arbitrary word can be tokenized in many different ways.

and they think in words

They do not. They don't even think in tokens. The process is: words are split to tokens, tokens point to an embedding position (latent space) while RoPE encodes a relative position, and all reasoning is done within latent space, which is not at all verbal (concepts are directions in latent space, and math is done on concepts, not words).

Also, a note: when spec'ing a generator, you need to know how much you're planning to use it vs. batteries. If it's only going to be used rarely, you prefer low mass, low volume, low cost, and low maintenance when unused (at the cost of low efficiency and higher maintenance in use), whereas if it's going to be used a lot, you prefer high efficiency and low maintenance cost in use, even if at the cost of higher mass, volume, cost, and maintenance when unused. In the former case, you'd prefer to allocate that extra mass, volume, and money into a larger battery pack.

That's why you don't use a tiny petrol generator? Diesel generator efficiencies are roughly:

Small backup generator (1-15kW): ~20-28%
Midsize backup generator (20-200kW): ~30-35%
Large industrial generator (200-2000kW): ~35-42%

Also, ironically this company's plan of the trailer providing a boost will actually make the tractor less efficient. ICE engines use "brake specific fuel consumption" (BSFC) graphs to plot their efficiencies across different RPMs and different torques. You can see an example for a small diesel engine here. Note that they require very high torque conditions and relatively high power conditions to be efficient. You can change the balance between torque and RPM within a given power band (blue) via gearing but gearing doesn't change what power band you're in. If you're in a low power band, you're fundamentally forced into inefficiency (note also that you're not going to be driving around at 1000 RPM just over a stall all the time).

Indeed, if you were forced into a low power band, you'd actually be better off with a series hybrid powertrain, as the engine can alternate between operating in an efficient powerband and shutting down. Of course, parallel hybrids are more efficient than series (albeit with added complexity and mass).

Unfortunately, the math doesn't work that way (even ignoring that a 400kWh battery is very small). Battery packs taper the closer you get to full, they're not a constant power all the way. Unless your battery pack can take 400kW at 80%, you're not charging that quickly.

Also, while 40 mins is fine in Europe (breaks: 45 minutes every 4,5 hours of driving... though using 70% of a 400kWh pack on a loaded class 8 truck going even at a slow 80kph will only take you 2 1/2h of driving in "average" conditions, so the truck's range is fundamentally undersized), the US is 30 minutes total break in 11 hours of driving, so ~6 hours on your first leg and ~5h on your second leg with 30 minutes to fill that 5h of driving. And US speed limits are usually faster for trucks than in the EU, so higher consumption. EU really needs 600kWh and >=600kW charging, while the US needs 800-1000kWh and >MW charging.

Note that in all of this we're assuming efficient-shaped trucks (Tesla Semi or the like), not your typical EU bricks, along with a well optimized powertrain and an efficient tyre config. If not, you need to increase those packs and charge powers further.

Wages and career prospects are a factor in what students chose to major in:
- Business and Finance: relatively easy courses, excellent career prospects and very good pay. Good social status too
- STEM: work long and hard to graduate. Wages are decent but in general there's not a lot of upward mobility (unless you go into management). And no one looks up to engineers.
- Academia: unless you love what you do, forget about it, because you're not going to get anything else out of it. Not even tenure, these days.

1. The same way 99% of content producers do it today. Less than one percent of youtube content is monetized in any meaningful way.

Would it benefit the public to completely do away with the other 1%? How could something like The Amazing Digital Circus have been produced purely on a hobby budget?

2. Word of mouth. Curated lists.

How does the producer of a video go about seeding "word of mouth" and getting onto "curated lists"?

3. The protocol already handles this.

Yes, by excluding a lot of viewers who lack an IP address that can accept inbound TCP connections, unless I'm missing something. It also excludes viewers who have an iPhone or iPad and don't have a Mac with which to build and ad-hoc sign an app because Apple has reportedly banned BitTorrent clients from the App Store.

The same way it all worked before youtube.

And how might that have been? I might be misremembering, but this was my recollection:

1. Movie studios and TV channels funded production of videos to be viewed by the public. Very few pitches got funded.
2. Movie studios promoted upcoming and newly released movies through television advertising, and TV channels promoted shows to the channel's own viewers.
3. Movies were paywalled, and TV was ad-supported (in the case of broadcast) or behind the combination of ads and a paywall (in the case of cable).

Also, before YouTube, most end-user devices on the Internet had an IP address, even if dynamic, which could accept incoming connections. Nowadays, a lot of Internet subscribers' devices are behind network address translation (NAT), and if you share your IP address with the whole neighborhood, the ISP is unlikely to forward a port to your device.

Under your proposal:
1. How would the producer of a video cover the cost of producing the video before it even reaches BitTorrent?
2. How would a viewer learn of a video that they are likely to enjoy?
3. How would the system work around users who "leech", or view the video without contributing to its decentralized hosting?

The military implications are obvious. Think Ukraine. If you suspect the enemy is trying to infiltrate on a dark night along several kilometers of frontline, you light up the scene while launching a bunch of low-cost FPV drones, and those infiltrators are about to have a bad day.

You *can* spot infiltrators in the dark with IR cameras, but it requires much more expensive drones and isn't usually as effective, hence the preference for night operations. Plus, there's IR camouflage, with varying degrees of success. But it usually makes you stand out like a sore thumb under illumination (you're basically wearing a tent).
