Closure library/compiler was the only real way to write a large SPA back in 2012+.
You had access to an amazing compiler with a standard library that was like having every npm module you could ever need but written by Google and well maintained without the security risks.
We still use it, and the only real “wish” we have is maybe if the jsdoc “type system” could just be replaced by TypeScript while maintaining all the rest of the library/compiler.
I helped start an early (1998) Australian ISP in Sydney (a modem bank connected to an ISDN line) with a Linux 2.0 infrastructure (Slackware…) and Perl based billing system running on Postgres 96. I was 16.
Been in the Web3 space as a side hustle for something like 2 years now and the only real usecase I’ve seen is something like USDC transfers over Solana.
Everything else is just a scam and/or ponzi.
Add to that that the price of coins is manipulated by market makers and exchanges (CEX and DEX) and it’s not looking good, honestly.
Regulation would actually improve the space a lot. Something like a national ticker for coins would go a long way to clearing out a lot of the scum.
