Going to New Zealand in two weeks... and I'm still not convinced platypuses are real, I'm pretty sure it's just beavers-with-strap-on-beaks.

Surely there is a toggle for that... somewhere?

I have the same with YouTube on my TV, always re-enabling English subtitles for Dutch videos, which... I don't want or need.

If you don’t pay for YouTube, you’ll get some unskippable ads…

Sooooo if a software conference doesn’t pay their speakers, should they be allowed to sell in-talk ad-segments? 😂

The only fear I have is AI taking away junior positions… creating a gap that new developers can’t easily bridge. We’ll only want medior/senior developers that create great code and the bots will write it all.

But how do we make sure there will be senior educated and experienced devs in the future?
