Exploration geophysics paid for me to travel to and across more than half he countries on the planet, calibrating old maps, datums, projections against the 'new' WGS84, scaling peaks to stage base stations, getting familiar with the ins and outs of tides, magnetic fields, gravity, radiometric backgrounds, finding a good band in Mali ...
Loved it.
Mawson had the field trip of a lifetime (for his two mates, it was the end of their lifetime!) and it didn't end his bug for the outside. I don't think he was made to sit in a lab.
I'd say your Mali trip was the same: it hasn't made you want to stop being outside from the sound of it.
I've "retired" to argriculture tech and labour support for W.Australian family grain production. We've almost finished harvest and I've been doing a lot of scrolling and posting here while hanging about near idle "on call" fire tenders (we had a hundred fires, mostly from lightening strikes, in a single week just recently)

^ Further south than I'm based, and a header fire, not a strike. Okay when caught early - life and town threatening if not.

The Mali trip was notable for random types firing weapons at our aircraft while we were running lines with 80m ground clearance - we had to armour the cockpit bellies and stuff the fuel tanks with mesh.
Datums can get dull fast but there's adventure inherent in surveying. You should write a book, or at least a chapter or two. "Nadir Point" has a nice ring to it...
Mine Camps .. with a Long S ( https://en.wikipedia.org/wiki/Long_s ) once appealed, but I fear getting cancelled.
There was always something happening, whether it was shipboard fires in the disputed parts of South China Sea or India / Pakistan engaging in cross border nuclear tests in our survey zone.
That last one followed several of us about for years, anytime we crossed a US controlled border they got interested in how we knew what they didn't ...

.. look, we just happened to be there with a 42 litre doped Sodium Iodide crystal pack and 256 channel gamma ray spectrometer just as the tests kicked off ...
I've done a fair bit in the field, but a huge part of my career has been mining old datasets and reinterpreting things in light of new data/etc.
What the article is describing isn't new in any way. But it also doesn't remove the need for fieldwork or the need for the experience of having done fieldwork to use existing datasets. Observational sciences (e.g. geology, biology, etc) where you can't easily replicate the environment you are studying in the lab are always going to hinge on some sort of fieldwork.
Finding creative ways to use existing data doesn't change that.
