120 MByte and not even capable of doing what a similar 1 MByte tool can do. Etcher is based on Electron. A browser(engine) isn't the most optimal software for many tasks (as are web-interfaces, but that is another rant), but Electron does just that. Haven't verified it, but I also read somewhere that Electron does collect a lot of telemetry data from systems it runs on.
The amount of resources Electron uses, the need or want of coders to only see Electron as their hammer to solve their (computational) problems with...it all feels so inefficient and 'bloated' to me. Almost like an unwillingness to do a bit more effort and create optimized code. After all, code is created once and used many times on many computers. Better make it as efficient as possible when it is still in the hands of the coder, so all it's users don't have to spend (time/energy) when the code actually runs. Because when code runs efficiency decreases run-times, which makes processes as a whole run faster. And time is money. Offset against the cost of running software, the costs for developing platform-specific software are a pittance.
Sorry, ranting again.
