Why do all existing tech ideas need a blockchain implementation?
Simple!
Speculative gains for the investors and free financing for the project. Let us assume that 90% of all ICOs these days will do absolutely nothing with the money, except spend it on Lambos and what not.
The way the ICOs work is quite simple. As an IPO (initial public offering) works on Wall Street, ICOs offer "shares" in the form of tokens. Tokens are just assets (tradable assets most of the time) that usually end up being worth 2,3,10, N amount of times more than what they were bought for (they are being pumped), before being sold by the investors (dumped) to take profit. They can ride the pump and dump game for as long as there is interest (most of the times accompanied by news). News can be good or bad (FUD).
There is no drawback for the tech providers (the company offering the token), as they receive well established coins (Ether, Bitcoin or some other crypto currencies or assets) that they can sell for fiat (real money -$, £ etc) which will support the growing needs of a tech startup.
The ICO space has become ever so crowded since mid summer 2017 and the rate that ICOs are published grows at an alarming rate.
It seems that every group of people that had an idea to implement are now moving from finding traditional investors to ICOs. There is a win-win situation for now (see previously made points), but there is also a concern that the market is becoming overly saturated with half-baked ideas (and I could name a number of badly thought or badly supported tokens after realease).
So moving back at the start of this article, yeah, probably 90% of these tokens will be worthless some day, but if 10% of them actually end up being used, then we, as a community and mankind as a whole, can take some major leaps in technology.
Who knows? Maybe decentralisation is possible in the end.
