This is such a terrible take. In any market with Chicken or Egg problem, someone needs to move first. Sure, they could have been more conservative in their approach (easy to see in hindsight), but to say they jumped in "without thinking" is pure nonsense.
You mentioned learning react and some other frontend tech. If you want a quick website, ignore those too and buy some theme with a known base (bootstrap). Then change the contents only, and not what it looks like.
