I work alongside a principal engineer who refuses to learn anything beyond what they learned 5+ years ago. It seems they got to the Senior level and just gave up learning. Makes no sense to me and is a detriment to all the more junior engineers in our team.
TEDx you mean. Which matters quite a bit, given that there are effectively no restrictions on who can give a TEDx talk :p
Which isn't to say that it's useless, just that the "TED" gatekeeping role isn't actually happening here, instead the gatekeeper is "people who have heard of TEDx", which is very different and imo quite a bit less useful.
Somewhere around 2005, most of my job as an Oracle DBA/developer for a pension company seemed to consist of writing small scripts to automate some process. Somewhat like little Unix daemons to do my bidding - hence the handle ”daemoncoder” :-)
I often joke that I'm just writing a small script to replace myself with.
Currently I do a lot of data wrangling and analysis, mostly in Python, so still plenty of small programs to automate the boring stuff.
digital tech is a small fraction of your emissions - reminds one of David MacKay's book:
Sustainable Energy – without the hot air.
In particular as Professor MacKay puts it: "Obsessively switching off the phone charger is like bailing the Titanic with a teaspoon. Do switch it off, but please be aware how tiny a gesture it is."
