Lava guitars; is this the future ???? .... !!!!!

I've been looking at their carbon fibre models for a while now. I've never seen one in person but if they are decent, they could just be the perfect busking guitar! I don't need all that fancy stuff though - I do appreciate the innovation behind it but more than likely it would just confuse me

I'm quite cynical about technology applied to traditional things.
These could be amazing for all I know, but experience has taught me if something 'aint broke, it doesn't need fixing.
Trying to pack as many different 'features' into something, almost always results in a jack-of-all-trades type 'thing', but master of none. If I really loved reverb, I would plug my guitar into a quality dedicated reverb unit. As I would for a delay, or chorus, or .... you get the idea. It is more expensive, but dedicated effects units/pedals are always better quality than some multi-effect do-it-all system.
I spent many years DJ-ing too, not just mobile disco type events (although I did that for over 20 years, it was a decent paid earner so why not), but played at early dance music events, and clubs, where DJ-ing skills are very important (mixing, scratching, beat juggling, and so much more). To do those things on two turntables with vinyl records, and to do them to a high standard, is actually incredibly difficult, akin to playing a real instrument. The modern way is to use a controller and software which plays digital audio, and not only does it require much less skill, it sounds much worse because of all the tricks, effects, and features of the controller & software. Too much all crammed into one thing, means nothing really stands out as being quality, it's simply quantity.
I feel the same about these guitars if I'm honest.

Sad to see that Rainsong Rainsong Guitars is closing down...
