There was a recent attempt at reading hieroglyphs from temple walls in Egypt using ML, but that failed spectacularly.

Despite having tons of high quality training data available, being announced with much fanfare and ample funding in 2018, it got completely pulled by now and even its website has been erased.

I am struggling to find any results apart from some of the initial marketing material:

I have briefly interacted with some people involved and the consensus was that its not realistically doable.

Therefore, although I do not doubt the good intention behind this prize, I am quite sceptical any results will come of it, as a seemingly simpler project with more resources failed to deliver.
