This isn't everyone's experience - I've got two precision laptops - they are 12 and 10 years old and have never shown so much as a sniffle of a problem, neither has my Latitude laptop that I lug around for personal use. Maybe I just got lucky ?
This depends, how many times does it need to hear the song to build up a reasonably consistent internal reproduction, and are you paying per stream or buying the input data as CD Singles - or just putting the AI in a room with the radio on and waiting for it to take in the playlist a few times ?
You're kidding right ? We're not footballers or athletes.. at 45 I feel like I only really started to approach the top of my game in the last 10 years and I've no desire to ease up or stop learning. There's an age bias that is quietly unravelling predisposed on IT as a whole being a young industry rather than because young people are better at it.
