Episode 30: Predictions for (the rest of) 2026 Happy new year!!! We know, we know, we’ve been in 2026 for a while already (already too long?). But this is the first episode we recorded this year, the first one with Levi as a dad (yay!), and one wh...

New episode of the one and only #GLaDpodcast. For this one, @rsfrankl.bsky.social , @levijohnwolf.bsky.social and yours truly dust off our oracles to speculate what 2026 (whatever is left of it anyway) has in store for Geography, Life, Geography Life, and Data!

AI is now definitely changing how we live our (geography) lives!

I gotta say I find a lot of AI discourse around higher ed very confusing. "if ChatGPT can write your essays is college even worth it?" did people think math teachers were assigning problem sets because *they* couldn't figure out the answers?

I've just had the most surreal experience: I googled a relatively niche question about an academic topic and got an AI response paraphrasing *my own* crossvalidated (the stats stack overflow) answer from years prior.

It is so constraining to write in a TUI... I'm finally admitting that git+vim+Hugo is a bit masochistic for me, and have moved blog.ljwolf.org back to Tumblr. Just having an iOS app already means it's 1000x easier to keep up to date!

Hence why the big platform firms push these things so strongly… just like PyTorch/Pyro/JAX+Tensorflow jockeying, these tools don’t *remove* friction per se, they displace it in the stack. I love llms for learners, but I’m not sold that they end this β€œfront” of the β€œlanguage war…”

I wonder whether this will make the *library side* of these debates even more winner-take-all? Lower barriers for users make it more important for language library developers to β€œkeep parity” with one another, and even possibly slightly ahead. It also intensifies the value of network/ecosystem!

For users, this is probably true! Who can be territorial when the most basic barriers to usage (like installation and familiarity) get ground down by Copilot-type things…but!

I never looked into it, but it’s a solid ideaβ€”Ron used to have this β€œclassics that weren’t” project w/ books/papers he thought were primed to be impactful but, for whatever reason, never were. That catmog and the associated paper about London housing is *very* ahead of its time.
