Any software ie Google, meta snap etc are very vulnerable as that smart guy in the garage can come up with something (tiktok) out of nowhere. That’s why meta for example has to buy the new threats (Instagram) however you can’t make Apple products in a garage that’s for sure or anywhere else for that matter as Msft, Google, Samsung, LG, Chinese phones have all tried to knock off Apple and have failed miserably.
Apple’s strength has always been its ecosystem, and it continues to grow with every new product release and software update. Replicating it is an uphill battle, and that’s why I believe Apple will continue to prosper for a good long time to come.
