For me, even with these layoffs, not everyone will lose their job. Amazon and other companies will keep valuable employees. This means that wherever you work, you must constantly improve yourself and give value unless you don't like your job and want to leave. Being valuable ensures job security, even in tough economic situations like now. If you're indispensable, companies won't let you go easily.
working in large corporation isn't as simple as just learning new things and automatically our value will sky rocket though, the company will try their best to improve their efficiency so occasional lay offs is to be expected.
even more so if they deemed that the company is just too bad in term of efficiency.
but I could also question whether this is the effect of AI being utilized into system, essentially improving efficiency while making big portion of employee redundant. I mean it could be, Amazon is among the one that I expect to employ AI into their system faster than the other because they have the infrastructure already, they even provided services for AI deployment in their AWS.
but at the end of the day, if we really want to be financially secure, we should just try to make it big through entrepreneurship.
