As time goes on, the value of the model will go down and the value of the tools will go up.

What's interesting is you might not want to see de novo AI-generated storytelling (slop factor), but you might really like the way AI can make a story crafted by humans more interactive.

Satellite signals are just weak RF signals and can be disrupted easily. There is nothing 'hardened' about them. It's funny that people think Starlink or any of its many incipient competitors are any different.

This is an incredible foretaste of what AI can enable in gaming. Not replacing humans (the creators here are former leaders from Minecraft), but rather simply unlocking more fun gameplay by offering creativity, humor, and branched storytelling customized to the player.

New comment by malchow in "Vertical Solar Panels Are Out Standing"

malchow — Mon, 29 Sep 2025 15:54:17 +0000

In addition to bi-facials starting to work quite well, HNers may be interested in a rising class of ultra-low-mass material that has come out of work at Stanford and Intel in transition-metal dichalcogenides (TMDs) (e.g. for MoS₂, WS₂, WSe₂, etc.).

It turns out these enable a very high specific-power PV cell that adds another even more attractive production curve behind what is happening in vertical bi-facials. See e.g.:

Cells are subject to aggressive binning – akin to the early days of MOS process. And specs and process capability adhesion in the industry are not as "serious" as they are in the modern, U.S.-led semiconductor industry.

Source: I work on 100% Si anode batteries constructed in part with a litho-derived laser process at Enovix.

Practically, shorter path silicon does nice things for power budget for a few minutes, that then gets totally obliterated by feature builders wanting to do cooler things!

100% active Si material in the anode. Not 5% doping of graphite.

Amazing.
