It is not necessarily untrue (source: am currently involved in battery R&D). However, the degree to which it is true will vary strongly based on the particular choice of chemistry, what sort of additives/agents are used (e.g. scavengers/getters), cell/pack engineering choices (protection against ingress of outside atmosphere and such), and so on and so forth.

Goes to show that having a creation date placed somewhere near the top of an article or blog post is a good idea.

Dear ChatGPT, how can I patch a hole in my sock?

As a side-gig I taught within the doctoral education program for several high-ranking universities in Europe for about a decade (over a thousand PhD candidates). My impression is that nearly all funding for PhD projects flows to fields like medicine, physics, chemistry, computer science, electronics, and so on. Spending on humanities is absolutely minuscule compared to those.

My first guess was that they used an external brick for the power supply with a relatively low output voltage--that would eliminate a lot of the CE test load. However, a cursory glance at the product photos suggests the power supply sits within the base of the lamp. Maybe the product developer can shed some more light on this. ;-)

Cells specialize based on the presence of certain chemical gradients, for example. These types of 'signals' that guide specialization already become apparent in a very early stage of embryonic development. I don't think that's part of the realm of epigenetics.

I can’t imagine anyone in my environment becoming really angry over this. Some of them would have to find new time sinks though—-hopefully ones that actually benefit them instead of turning them into commodities.

Don’t agree with this take; software doesn’t need repairs when you drop your phone, when it is submerged, when it is charged/discharged daily for a few years, and so on. Freedom to use your hardware however you like is more of an ideological discussion, whereas repairs are simply necessary due to the unavoidable wear-and-tear.
