The exponential part is going to trip up most of this. In the best scenarios you might get that for a very short duration of time in a segment and then see a continued, very slow decline in costs.

Space launch costs, thanks initially to SpaceX pressure.

Wireless and wired broadband access costs per bit continue to decline persistently globally. Satellite broadband costs are about to do a hard one-time plunk as Starlink comes online (another example of the short lived nature of the biggest drops).

The cost of entry for a decent virtual reality experience vs the value potential or value derived. The hardware requirements vs the median machine has adjusted massively in the Oculus era and the quality of the software will continue to persistently improve over a long period of time.

The cost of lithium-ion batteries $/kWh.

Stock trading

My 11 year old brother trades stocks Not sure if that's what they meant by free market

If he's doing it based on valuation models he's created and 10-Ks, why not. Might be a fun math exercise if he has money to burn.

Apparently on field DNA testing https://www.nytimes.com/2019/10/27/us/politics/dna-tests-bag...

Ehh, not really for any appreciable amount of sequencing, w've been pegged right around ~$1000/human genome for a while now [1]. The machine mentioned in the NYT article is almost certainly a variant of Thermo's RapidHIT system[2], which is not DNA sequencing.

How do you trade stocks with the amounts of money a typical 11 y.o. has?

The Wikipedia page on Moore's law includes similar observations.[1] For example, the DNA sequencing cost.[2]

And another list that features laws, some of which describe exponential processes.[3]
