If you were to have an environment in which H2 would actually make economic sense, non-H2 storage and distribution systems would be even cheaper, and they can be added incrementally rather than needing a big bang, preventing investing in H2 from taking off in the first place.
However, as seen above, there are lots and lots of ways to store (or equivalent) power over long periods, it's just the economic incentive to build them that is needed - and is now on the way. Renewable-gas low-duty-cycle gas peakers, Carnot batteries, and sodium-ion batteries are top candidates, with the first being the low-hanging fruit because they already exist.
The real issue is the cost of keeping gas peaker stations around that are mostly idle and fire up only a few days a year, but that's an economic issue, not an engineering one.
In the longer term, you could even run them off net-zero renewable syngas that you make the rest of the year using low-cost electrical power at peak solar generation times; you only need to store a relatively small amount of it, and old fossil fuel reservoirs are ideal for this.
Don't knock small gains like this. Even a couple of percentage difference is worth having; all the marginal gains add up to make large scale gains.
But even that is still worth saving - it's a few percent more benefit for electrification.
I hope that efforts are being made to make sure that its content is not only being archived in many places, but also that the know-how to reboot Wikipedia's hosting from its dumps (software, infrastructure deployment and all) is being actively preserved by people independent of the organization.
Battery storage isn't quite where it needs to be, yet, so there's still some need for fossil and nuclear power, but when it is, decommissioning the remaining fossil power system is a no-brainer, and those with the biggest existing solar and wind estates will benefit most, and fastest.
You can get an awful lot done very quickly in C if you aren't bothered about security - and traditionally, most of the profession has done exactly that.
I don't we can make any conclusive verdict about the promise of ML for radiography right now; the life-critical nature of the application it's in the unusable middle, but it might get better in a few years or it might not. Time will tell.

John Baez's Crackpot Index (1998):
I recently almost fell on a tram as it accelerated suddenly; my arm reached out for a stanchion that was out of my vision, so rapidly I wasn't aware of what I was doing before it had happened. All of this occurred using subconscious processes, based on a non-physical internal mental model of something I literally couldn't see at the moment it happened. Consciousness is over-rated; I believe Thomas Metzinger's work on consciousness (specifically, the illusion of consciousness) captures something really important about the nature of how our minds really work.
What is indisputable is that LLMs, even though they are 'just' word generators, are remarkably good at generating factual statements and accurate answers to problems, yet also regrettably inclined to generating apparenly equally confident counterfactual statements and bogus answers. That's all that 'hallucination' means in this context.
If this work can be replicated, it may offer a way to greatly improve the signal-to-bullshit ratio of LLMs, and that will be both impressive and very useful if true.
