0I know, nowadays everyone uses internet if they want to learn something or want some information about something.
In my opinion, when you start to learn online, the 1st problem you'll face is, you won't know where to start or when to proceed with lessons. You assume that you are playing correctly as no one is there to evaluate your progress.
I have many students who started learning guitar from YouTube. And honestly speaking, teaching those students is more difficult because over time, they have developed wrong techniques. Correcting those wrong techniques requires a lot of time and patience.
I think that everyone should learn at least the basics of a real teacher. Once you get the basics right, then the internet is always there to help you explore new things 😉
