Why are people saying more people needed to run Twitter? Whatsapp was handling billion messages on new year eve with 55.

Whatsapp was handling billion messages(infact more I assume) on new year eve with 55 engineers and that was before Facebook acquiring them. A guy from Poland or some country single handedly created Adobe photoshop alternate. Plenty of fish dating site was built by one person and he sold it for 150+ million dollars decades back. Literally one person. Notion app was built by literally <20 engineers or so just few years back.. If the engineers are really rockstar ( someone who knows syntax in and out, have strong basics of the stack they are working on, and have fire to crush things to market and hit it hard), then I feel less engineers can make impact. But what happens is generally - engineers google up for writing basic inner join queries ( I do that a lot. I'm below average or average engineer and heard from a Google engineer that they do it too- but may be that googler is one-off hopefully). - they don't have strong muscle memory of the programming language they are writing in. If they are ramping up, then its much worse. THis is the place where lot of things slow down. While we converse in English we are much faster because we already know the words and grammar. We don't google or look for words... - I feel the JIRA, Agile, Scrum as utter BS. It took 3 hours to set JIRA board for a sprint * things up tickets , * assigning story points, * description of each ticket, * what QA needs to do for each ticket, and * then 30 mins sprint kick off, * 30 mins sprint review - Almost 4 hours gone which is half a day. Yeah, people will say these are needed when company grows or for cross functional projects etc. But if a team has solid requirements done, at least majority senior engineers on same line for a project, a decently written TDD/API spec, demos to check about the progress and establishing trust among engineers(which still needed when above paragraph steps are done) we can cut down lot of stupid steps and move faster. Things like code review, infra still will happen, but much more faster pace...This extra maintenance ticket management is just a useless work. TLDR: I strongly feel the "processes" in tech industry is what first needs to be disrupted. The entire Agile scrum shit came from Japan automobile industry and assembly line concept which is 20 years old and was never questioned... I don't know why no one challenge and fight against "Status quo" on the processes tech companies follow, but the companies BS around saying "status quo" things around you is our company culture. If the team could find better way to manage themselves and the project cutting down BS things, tech industry may become efficient like Whatsapp, Notion and other startups. I have tried to break it in my current company (not mu-sigma), as usual managers says I'm up for it and 2 hours later asks for sprint metrics 🤦‍♂️ End of rant. #tech #tech #tech #tech
