Python
From scripting glue to the default language of data and AI. Readability as a growth strategy.
Python stuck because readable syntax lowered the floor for scientists, students, and ops refugees alike. NumPy, Django, and PyTorch built moats no syntax fad could breach. It is slow on purpose and fast enough for where the industry actually spends money.

Context
The browser ate the desktop
The web became the default delivery surface. LAMP and Rails made shipping cheap; Ajax made pages feel like apps; SOAP/SOA tried to enterprise-ify the wire. REST won by being debuggable with curl. This decade invented the modern product cadence — and the habit of treating every new framework as destiny.
