Imagine if all the hundreds of billions of dollars being pumped into AI was given instead to artists, writers, musicians. If/when the AI bubble bursts, everything will get crappier, but you give that money to artists: no bubble, just a world more humane and human in a million little ways.

Five tin chilli

It’s not chilli and it doesn’t use five tins. Blasphemous in any number of ways and moderately dangerous to prepare, is is nonetheless easy to make and oddly satisfying.

I'm old.

If you're not, listen to this.

Get a guitar or some drums, or a trumpet. Pick up a brush, a pencil, some clay or a welder.

Just make shit. It doesn't have to be good (eventually it will be) just make music, art or write or whatever.

It's literally never been more important.

Let's compare our world models. I find that different people seem to have rather distinct internal world models. E.g. I personally have neither visual imagination nor an inner voice, found it weird others do. Here is a quick google forms to check idea:

30 years is used for calculating climatologies and as a standard for comparison. It's eminently practical, that's why it's used. The difficulty comes if you think that 30 years is what climate is.

The thirty year period is a sort of convenient compromise. For some variables it is longer than it needs to be, for others shorter. And yet, it’s become this weird magic number that somehow “defines” climate.

It’s that time of year when we celebrate the celebrated, reward the rewarded, and cite the cited in a game everyone knows is meaningless and rigged.

I nodded off in a meeting and had a dream about sticking together the heads and tails of a bunch of worms that had got chopped in half. That became a new way for combining climate data sets.

Probably a terrible idea
More bad ideas for sticking datasets together like wiggly worms.
