I see a lot of parallels between ML/DL and cryptocurrency research.
We're thinking very hard about if the price of our deep-lolcoin is going to go up enough to buy a new a vacation house....
The criticisms of the financial industry where they are not really creating anything of value other than optimizing more value out of existing money.
Adtech industry where a whole generation of technical researchers spent time figuring out how to optimize clicks.
Cryptoeconomy and blockchain where large amounts of money are created out of perceived value and gargantuan efforts are made to build, not solutions to real-world problems (yes I know there are some), but ways to increase the shared, total value of the technology or individual cryptocurrency.
