I can't believe how good AI is getting. A year ago my whole stack was a $20 Cursor sub. Now I have Opus 5.5, GPT 6 Sol, GPT 6 Astra, and Fable 5.1. Astra one shots my backend. Fable handles my front end. Opus 5.5 and Sol dropped on the same day and made frontier intelligence affordable. Things that used to take a team and a month now take one person and an afternoon. The world is changing and it is not slowing down anytime soon.
