I am more comfortable calling it the increasing competency of the workforce needed but the existing resources are not like that, now digitalization in many sectors is no longer a public secret that the demand for competent and competitive workers by following the civilization of the times is very much needed so that the feasibility is indeed questionable.
Meanwhile, he did not state in detail geographically to state that, although it sounds like a piece of unfinished advice.
Yeah right, the level of competition in terms of having that kind of job is very demanding there are online and offline venues where you can perform whatever skills that you acquire, you can always take your chances as the needed workforce are just around if you know well what skills you can offer, though it's a tough competition but you have that capabilities and you know that you can do better you always have a good place to work.
Not everyone have that opportunities and like what OP mentioned, acquire skills to improve your chance meeting what's needed to land yourself a deserving job.
In fact, this world is running very dynamically, developing and continuing to develop until it meets the progress of civilization that continues, of course the demands of the era regarding labor must also increase and so someone cannot stop having such lagging abilities, we must continue to develop our abilities to survive with very rapid technological advances, if we are left behind then no one wants to employ us if our basic is a worker, but if we are an entrepreneur we should be more able to accept a development of the era and make it a potential to get greater opportunities in business, we must have glasses in walking in this world which is very fast lately.
You have an option to create your own business and use the technology to help you establishing your opportunities, with how the technology keeps on improving you need to adjust and make sure to adopt in order for you to take advantage of everything, though if you are just an employee you needed more the upgrade from your skills as there are many competitions that you need to compete to land a job that suits you, you can't stay as it is as the demand is everywhere but the qualifications keeps on being tight to a deserving individuals.
