Insane how one person just get idea and is able to start writing technically impressive hard project.

Unlimited resources, time, smart people. Still hard to imagine which company can replace / will replace them.

SPAs should not be used for something serious. Maybe used them to some fancy ecommerce / hype webpage, but that is their limit.

Impressive.

16years 52M active user per month 100k communities (/r subdirectories) 100M$ in second quarter (3x more than in previous year)

10-15B$ valuation (with current rate of inflation, possible target)

Curious about final IPO, is pretty challenging to live these days with meta, crypto, nft, inflation and memes everywhere. Better to go IPO quickly.

This is true at least in 2021. PHP is evolving, going with more strict data types (method return types, variable types), lot of new language constructs like implicit constructor parameters, spread operator ... but it is still interpreted language. For small to medium projects (like 10k - 600k LOC) with tens of millions visits per month it could be easily primary language.

Just my 2 cents, better starts with PHP, because you can relatively fast see some results instead of starting new project with RUST / Go / Crystal / Elixir or whatever is currently in hype and you are not sure if selected language have all requirements you need in your project.
