I worked at a different MAANG company and saw internal slides showing that they planned on being able to replace junior devs with AI by 2025. I don't think it's going according to plan.
At the end of the day, one thing people forget about with these things is that even once you hit a point where an AI is capable of writing a full piece of software, a lot of businesses will still pay money to have a human read through, validate it, and take ownership of it if something goes wrong. A lot of engineering is not just building something for a customer, but taking ownership of it and providing something they can trust.
I don't doubt that eventually AI will do almost all software writing, but the field of software companies isn't about to be replaced by non software people just blindly trusting an AI to do it right (and in legally compliant ways), anytime soon.
Man, if you're going to start gatekeeping about pointless tech than a fitness band is also pointless.
Go out and run til you're tired and eat right and you'll get fit.
