People are getting fired constantly as companies move to automate more jobs, everything will end eventually. I don't think it is nuts.
A 'real' job should give you some notice, may give you a payout and may help you find another one. A gig on here will simply vapourise. For many that'll be fine, it's play money. If you're feeding your ten kids then it's a problem. And these things are cyclical. There may be no other avenues out there if the whole scene is quiet.
